Watching Slice speed across streets and leap over stairs and cement planters, it's not hard to extend that image and envision him defying gravity, fluttering toward the sun. For many of Peterson's friends, skateboarding and multiple tattoos go hand-in-hand. But Peterson sports only one small example of body art. It's a simple, roughly drawn outline of an airplane on his hip. "I always think that if I had one wish, it'd be to fly," he says, spinning the wheel of the skateboard he's hugging to his chest. "Maybe that's why I do this."
