New Way for Teenagers To See if They Bounce
By Anna Bahney
SIX members of two restless clans called the Street Ninjas and Gravity Pac circled each other at Grand Central Terminal last Sunday. Each group sniffed out the other, taking in numbers, collective stature and most important, sneakers (mostly a collection of Adidas and New Balance). Satisfied, the Ninjas, from New Hyde Park on Long Island, and the Pac, from Putnam and Westchester Counties, started clasping hands, knocking elbows and throwing down French slang. ''I didn't do any parkour last night, because I knew I'd be doing it all day today,'' said Ben Gartman, 15, a Pac member from Cortlandt Manor, N.Y., as he rocked back and forth between the balls and heels of his feet. Andy Kelly, 17, also from Cortlandt Manor, started toward the subway. ''We have three other traceurs with us, but they couldn't wait,'' he said. ''They're downtown already.''
