First there was Northern California, where the annual three-day Kinetic Sculpture Race began in 1969, the summer of the legendary Woodstock Festival.
Then there was the American Visionary Art Museum, which began its 15-mile Baltimore Kinetic Sculpture Race in 1999.
Yesterday, Philadelphia, the city of firsts, clinked and clunked its way into history.
A bit late.
It was the first Kinetic Sculpture Derby, an hour-long parade of eight bicycle-based contraptions through three miles of the streets of Kensington.
"It's not a race," said derby spokesman Kevin Musselman, 22. "It's a test of endurance, artistic ingenuity."
Musselman powered one of the smallest entrants - a two-person bicycle laden with more than 50 small white balloons - while he and a companion wore pink jumpsuits and pig noses.
"The balloons are serving as our clouds," Musselman said. "We're flying pigs."
The derby was staged a block from Frankford and Susequehanna Avenues as part of the Trenton Avenue Arts Festival.
The event showed the jewelry, clothing, ceramics and such of about 80 entrants on a blocked-off section of Trenton Avenue.
Perhaps the most flamboyant derby entrant was staged by Andy Dyson, 47, executive director of Neighborhood Bike Works, a nonprofit agency at 40th and Locust Streets.
"We get donations of used bikes from the community," Dyson said in an interview. In after-school and Saturday programs, "each kid learns how to fix a bike and gets to keep it. . . . We hope people learn working in a team, problem solving."
Flamboyant? Oh, yes.
How about a two-headed, 10-tailed bird that, Dyson said, consisted of "two tandem bicycles welded together - four wheels, four riders."
Oh, and flapping wings, too.
Followed by a 10-person pit crew on nine other bikes, with most of the 10 helpers wearing papier-mache birds' heads.
And they were needed, Dyson said after the race, because on a cobblestone street about halfway through the derby, "something broke and we had to hammer it back together."
Flamboyant might define the nation's other kinetic contests.
The self-styled oldest is to be run Saturday to Memorial Day from Arcata to Ferndale in Humboldt County, Calif., 200 miles north of San Francisco.
In a Friday phone interview, Shaye Harty, president of the nonprofit Kinetic Universe Inc., said one of the 35 expected entrants this year is called "The Deliverance Truck."
On a bicycle chassis is what looks like an old delivery truck. "There is a kinetic grandma on top of the sculpture," she said, "in a rocking chair, [a grandma] with moving arms."
Harty spoke of other kinetic sculpture events in Corvallis, Ore., and Prescott Valley, Ariz., but knew of only one on the East Coast - in Baltimore.
On Trenton Avenue, Bob Phillips made a stir as he steered his iron-wheeled bike along, a 60-pound skeleton moving arms and legs over the front wheel.
A Fishtown metalworker who graces his railings and grilles with artwork, he called the skeleton "a dragon from hell."
Hmm. And his age?
"I'm 46, going on 17."
