Argentine-Uruguayan collective Bajofondo performs at The Rialto.

Our picks for the top entertainment events of the week

UPDATE: Bajofondo concert cancelled.

Bajofondo serves up tango-electronica fusion

Led by Grammy- and Oscar-winning producer Gustavo Santaolalla (Juanes, Café Tacuba, “Brokeback Mountain,” “Babel”) on guitar, vocals and percussion, the Argentine-Uruguayan collective fuses tango with electronica. But this is no mere two turntables-and-a-microphone group. With Santaolalla on guitar, vocals and percussion, the rest of the octet contributes the usual (bass, keys) and the unexpected (bandoneon, violin), intermingling the acoustic and the electronic. Not traditional tango, not traditional electronica, Bajofondo is a danceable mixture of the two. When: 8 p.m. Thursday Where: The Rialto Theatre, 318 E. Congress St. Price: $23 Info: 740-1000, www.rialtotheatre.com

The Tucson Audubon Society is looking for birders to help raise money for the organization this month through its Birdathon, according to a news release.

“Birdathon is similar to a charity walkathon where walkers earn donations for numbers of miles walked. Instead we count birds,” said Chris Harrison of the Audubon Society, who organized the event.

Birdwatchers will gather in teams from now until May 10 to count bird species in specified areas. Donations will be raised through pledges of money for each species spotted or a flat donation.

Birders can create their own teams or join teams organized by the Audubon Society, the news release said.

For more information, see the Audubon Society Web site at www.tucsonaudubon.org or call or e-mail Harrison at 629-0757 or charrison@tucsonaudubon.org.

Are you a kid who likes to create edible concoctions?

Show off your skills at the Healthy Kids Day Teen Iron Chef competition Saturday from noon to 2 p.m. at the John Valenzuela Youth Center, 1550 S. Sixth Ave.

Teams of six teens will battle one another in creating a healthy snack within an allotted amount of time.

The winning snack will be chosen from a panel of celebrity judges, and prizes will be awarded.

The competition is organized by University of Arizona library science students, said Sol Gomez, librarian at the Sam Lena-South Tucson Branch Library, who is helping with the event.

Participants won’t know until competition starts what ingredients are available to them.

“They will come up with healthy snacks, something they could put together when they come home from school, that taste great,” Gomez said.

To register for the competition, call 594-5265.

Speedy pigs compete for ice cream at county fair

Cook's Racing Pigs speed around the track to win soft-serve ice cream with Oreo cookies.

The 90-foot horseshoe racetrack is laid out ahead. On one end, the starting gates are being loaded; on the other, soft-serve ice cream with Oreo cookies awaits the victor. The starting gates rattle as the athletic animals become anxious. Similarly, the tension builds in the crowd. Suddenly, the gates fly open and they’re off!

Screaming Yellow Oinker, Go-Go Green, Pork-Belly Blue and Speedracer Red tear around the track as spectators scream for their champions.

“The racing pigs is an event that just about any age group will enjoy watching,” says Launa Rabago, marketing director of the Pima County Fair, which kicks off April 16. “(Audiences) think it’s funny and entertaining. I haven’t ever recognized that pigs appeal to any certain age demographic, so we consider it an event for everybody regardless of age.”

“Cook’s Racing Pigs” at the Pima County Fair is just like any other day at the races, the pig races that is. Before each race, audience members pick a color, yellow, green, blue or red. These correspond to one of the pigs in the race. Once the race is finished, everyone who picked the color of the winning pig is awarded a blue ribbon – that proudly declares, “My Pig Won!” – and entered in a drawing for hats and shirts.

“It’s a memory that we’re able to create for the spectators at the Pima County Fair,” says Charles Cook, owner of the pig racing company. “Some folks have never won a blue ribbon before.”

Cook, 48, raised pigs as a child and teenager in the agriculture organizations 4-H and FFA. At the age of 26, Cook, whose mother owned an ice-cream shop, was asked by a representative from the California State Fair if it would be possible to train pigs to race. As it turned out, all it took was cookies and cream.

“They are very motivated by the dessert,” Cook says. “Whoever gets there first gets more, so that’s their incentive to outrun the others. They actually change positions and you can see that they’re trying hard to get there first.”

Cook’s racing pigs are different from other porkers seen around the fair, he says. Rather than being meaty and muscular, the wild breed pigs he purchases are smaller and thinner. This ensures they can fit in the starting gates for as long as possible.

Cook buys the pigs once they are weaned from their mothers – and the training begins.

“In the first day of training they walk around the track until they realize they have that reward at the finish line,” Cook says. “Then the second day, they jog. And the third day, they run.”

Once the pigs have become seasoned competitors, they tour the country, competing with one another for that grand prize of ice cream and cookies. Each pig’s career lasts about one year or, “as long as they can fit in the starting gate,” Cook says.

As is the case with any athlete, there comes a day when the pigs realize they just aren’t what they used to be. Once the racers have passed their prime, they are retired and sold to anyone wanting a legendary racing pig. Cook generally buys only female pigs and tries to sell them to breeders to create the next generation of competitors.

As far as his own retirement, Cook says he and his family still have a lot of races left in them.

“We’ll be doing this until we’re physically too old to travel down the road and our new 9-month-old son will take over the business in the future.”

Pig racing is a family affair for the Cooks, who say their 9-month-old son will take over someday.

Reality TV star and '80s rocker Bret Michaels will perform at the fair on April 25.

Examples of some of the items from the Berlin Airlift

The Berlin Airlift of 1948/1949 was many things. It was the first major clash of the Cold War. It was one of the greatest humanitarian efforts of all time. It was a clever solution to a problem that easily could have led to bloodshed.

“I think the alternative looked very close to World War III,” said retired U.S. Air Force Gen. T. Ross Milton.

The 93-year old resident of the Splendido retirement community in Rancho Vistoso was chief of staff to the general who organized the massive effort.

Starting Tuesday and lasting through May 10, the Pima Air & Space Museum, 6000 E. Valencia Road, is hosting a traveling exhibit commemorating the 60th anniversary of the Berlin Airlift. “The Berlin Airlift – A Legacy of Friendship” tells the story of the airlift through text and historical black-and-white photos.

“In 1948 and 1949, the United States and her allies saved more than two million men, women and children in West Berlin when the Soviets blockaded the city,” Bernard Otremba-Blanc, the German honorary consul in Arizona said in a written statement. “The Airlift created a legacy of friendship between the American and German people.”

The Soviet blockade began in June 1948 and ended May 1949. The airlift began in July 1948 and continued through September 1949.

Before the end of World War II, the Allies had agreed to split Berlin into four sectors, with the United States, the Soviet Union, France and Great Britain each controlling one quadrant. Berlin was deep in the Soviet-controlled part of Germany, but the Western allies expected to be allowed access to the city.

In May 1948, in an attempt to force the West out of Berlin and force the citizenry to accept communism, the Soviets blocked all rail, water and highway routes through East Germany to West Berlin.

The Americans weren’t going to leave, short of being of forced out by war, but the allied sectors of Berlin had less than two weeks of food and other necessities on hand to sustain its two million inhabitants.

With all other routes closed, the U.S. came up with the idea of bringing food and other goods into West Berlin by air.

According to a Pima Air & Space Museum media release, during the 11 months of the Soviet blockade, the U.S. Air Force and the British Royal Air Force flew a combined 277,569 missions over Berlin, delivering 2,325,570 tons of food, fuel and supplies.

Several Air Force veterans who played roles in the airlift now make their home in southern Arizona.

Retired Air Force Col. Bill Lafferty of Green Valley flew one of the earliest flights of the mission, although he didn’t know it until a superior told him so afterward.

“‘Congratulations. You just flew the first mission for the Berlin Airlift for the group,’” a colonel informed the young Lafferty.

Retired Air Force Col. Gail Halvorsen of Elephant Head is famous as the “the Candy Bomber” for his drops of gum and candy to the children of Berlin. Although the drops were initially unauthorized, the program got the approval of the brass and provided not only sugary treats but a morale boost to the people of Berlin. It was a sign that somebody on the outside cared about their plight.

“The candy represented hope,” Halvorsen said.

Milton, however, played an even more central role in the airlift. He served as chief of staff to Maj. Gen. William H. Tunner, who was put in charge of the airlift shortly after it began.

“Tunner was the guiding genius behind the way we got through that mission. I was his chief of staff, which I had been for three or four years, so I guess I was the number two fellow there,” Milton said.

The logistical challenges were enormous. At the peak of the airlift, planes were landing in Berlin at the rate of one every 45 seconds.

“We couldn’t have possibly done the tonnage that was required to keep Berlin alive without some innovative operational practices and we devised those as we went along,” Milton said. “You could look at the airlift as kind of a giant, endless belt of airplanes, all flying at the same speed, at prescribed altitude and if they missed their approach in Berlin, they had to come home. There was no tolerance for circling and making another approach. That would have broken the belt.”

The tremendous effort by American and British forces met the Russian challenge while avoiding all-out confrontation.

“I don’t know what would have happened if we had decided to force our way in on the ground,” Milton said.

Anne T. Denogean can be reached at 573-4582 and adenogean@tucsoncitizen.com. Address letters to P.O. Box 26767, Tucson, AZ 85726-6767. Her columns run Tuesdays and Fridays.

One of the hundreds of American planes like that flown by retired Air Force Col. Gail Halvorsen of Elephant Head lands in Berlin in front of children caught in the Soviet Union blockade.

Jim and Karen Kremsreiter, of Baraboo, Wis., look over the exhibits in the traveling Berlin Airlift exhibit at the Pima Air & Space Museum.

Expo returning for the second year downtown at Hotel Arizona

Jon Lewis of 4 Forty 4 Tattoo does a skull tattoo on the back of Travis Shipley, 27, during last year's Tattoo and Blues show and contest at Hotel Arizona. This year's event will be April 10-12.

Tattoo artists will ply their crafts April 10-12 at the second Tucson Tattoo Expo at Hotel Arizona, 181 W. Broadway.

The event will mix local artists with tattoo practitioners from California, New Mexico and as far away as Hawaii and Virginia.

The expo is a homegrown event put on by local tattoo artists Jon Lewis and Mike Davenport. It will feature 40 booths with tattoo artists and 10 vendor booths with clothing, accessories and tattoo supplies.

Lewis and Davenport estimated that last year’s expo drew 2,000 people.

“I was tattooing the whole weekend,” said Lewis, who owns 4 Forty 4 Tattoo, 444 E. Sixth St.

Tattoos have become fully mainstream in the past decade or two.

“There’s not a stigma placed on this any more,” Lewis said. “Every demographic range has artwork on them, basically a tattoo.”

A Harris Poll survey in 2003 found that 16 percent of Americans have tattoos. A 2007 survey by the Pew Research Center found that more than one-third of Gen Nexters ages 18 to 25 have tattoos. A 2004 survey by the American Academy of Dermatology found that 24 percent of people between the ages of 18 and 50 have tattoos.

“The main purpose of the expo is for people to get tattooed by artists they have not seen before or been aware of,” said Davenport, an artist at Big Brother Tattoo, 3010 E. Grant Road. “(The tattoo artists) are qualified professionals that work in professional shops with reputations.”

The expo will have a late-night after party April 10 at Hotel Arizona featuring local bands and Black Cherry Burlesque. And local clothing shop Razorz Edge, 427 N. Fourth Ave., will put on a fashion show at the expo at 5 p.m. April 11.

“All of this stuff is so interrelated,” Lewis said. “What we do is in every facet of the world right now.”

“This festival continues to be the most popular Earth Day event in Tucson,” said Pamela Beilke, chair of the Earth Day Festival.

Another event will be the alternative fuel vehicle show. It will feature vehicles that run on alternative fuels such as biodiesel, compressed natural gas, electric, ethanol, propane and even waste vegetable oil.

Along with the alternative fuel vehicle show, those who have volunteered with Tucson Clean & Beautiful (TC&B) will be recognized.

Bethany Hontz from Saguaro National Park will recognize those volunteers who battle buffelgrass.

There will also be performances by the Retro Rockets, Alumni from Utterback Middle School and the Shadz Band. The Retro Rockets, a 60s Rock and Roll tribute band, will play songs by The Beatles, The Yardbirds, The Turtles, the Byrds, The Young Rascals and Roy Orbison. The alumni band will play swing music.

PHOENIX — Some visitors to the popular Luke Air Force Base air show were left frustrated and disappointed by traffic jams, a lack of parking and long lines at security check-ins.

About 90,000 people showed up for the March 21 air show, with an additional 125,000 on March 22, according to air-show director David Edwards.

Traffic was funneled down Glendale Avenue to parking lots, with delays in some cases as long as two hours. Electronic signs directing traffic were not always visible, and some contained wrong information.

“It was a frustrating experience for a lot of people,” said Scottsdale resident Evan Klein, who made it through the traffic maze and paid his nonrefundable $10 parking fee.

Klein turned around and left when he came up to a winding line of what he estimated to be more than 1,000 people trying to get through security and onto the Glendale base.

Klein said he had been looking forward to the air show for two years, but the private pilot and his family ended up watching a couple of performances parked along the side of a road.

The second day, Glendale police made adjustments including increased manpower, said police Lt. Brian France, who handles special-events planning for Glendale police.

Luke identified parking and hired private contractors, but “ultimately, a traffic plan has to be submitted to our transportation department,” France said. France said he and Luke officials already are talking about how to improve traffic at the next air show.

France said a record number of people attended the air show and began arriving earlier than expected.

One of two parking lots at Glendale Municipal Airport, which used a private shuttle service to take visitors to the base, did not have enough drivers scheduled early on Saturday, France said.

Plus, shuttle buses got stuck in heavy traffic.

More drivers were added and shuttle buses eventually were given police escorts.

Bruce Bayly lies on a bed of 400 nails at a past Physics Phun Night

There are three words Tony Pitucco doesn’t want to hear when he’s lying on a bed of 400 nails: Do it again.

“Kids always shout ‘Do it again!’ but you really don’t want to do that one again,” said Pitucco, laughing. “You only want to lay on nails once a year.”

Pitucco is the man behind Pima Community College’s annual Physics Phun Night, which is in its 13th year of showing that science is fun.

The show will begin at 6 p.m. Friday at PCC’s West Campus, 2202 W. Anklam Road, in the Center For the Arts Proscenium Theatre.

The Pima show is an offshoot of a similar family-friendly physics function offered by the University of Arizona each fall.

“The things we do are rather remarkable because they are outside of common sense,” said Pitucco, chair of the physics department at PCC’s West Campus. “We have a bunch of standby experiments with liquid nitrogen, lasers, aerodynamics and the kids really get into it.”

About three years ago, Pitucco and Bruce Bayly, a UA mathematics professor and Pitucco’s partner in physics crime, decided to put the experiments into skits. The skits feature Pitucco, Bayly and a Raytheon engineer who was once Pitucco’s student at Pima.

“There’s an evil scientist, of course, and a good scientist and this year it will be pirates that are going from one island to another trying to solve the mystery,” Pitucco said. “We’re extremely bad actors, but we have no embarrassment and no shame at all.”

This year’s show – titled “The Pirates of PCC” – will also have extra experiments and demonstrations in the campus’ parking lot, courtesy of the Physics Factory Bus.

“Some of the experiments we can’t do in the auditorium because of fire and things,” Pitucco said.

The purpose of the annual event is to engage students in science and to explain that while science can be hard, it’s also really fun, said Pitucco.

“We want kids to see scientists having fun,” he said. “And it works because after the show you can’t stop them from storming the stage with questions. You can keep them there until almost midnight.”

People attending Friday’s Physics Phun Night will have the opportunity to ride a hovercraft, see liquid nitrogen freeze flowers or tennis balls and, of course, see the bed of 400 nails.

Pitucco said he and Bayly take turns lying on the bed, which demonstrates how pressure is distributed across an area. Another bed of nails is placed on the person’s chest. A brick is placed on the top bed and a Pima student is asked to break the brick with a mallet.

“If there was just one nail, it would be bad, but with a lot, it isn’t painless, but it is distributed,” Pitucco said. “Still, you don’t want to do it more than once a year.”
