You see something that looks out of place in the row of fancy, chrome-covered motorcycles. A small, rusty minibike is in the corner, covered with decals and stickers. It has a lawn mower engine for power, and the whole thing looks like it was cobbled together from a junkyard. Still, there's something about it that sparks your curiosity.
You squat down next to it and try the twist-throttle. As soon you your hand touches it, you find yourself outside in the hot sun. Blinking, you realize you are in the middle of a trailer park, surrounded by scruffy-looking boys that range from maybe 8 years old to a goofy-looking 15 year-old with red hair, lots of freckles, and buck teeth. You are still holding the minibike's throttle, but it looks bigger than before, and your hand is small and slender, and freckled.
Freckled? A glance down shows that you are obviously a boy yourself, with a body that is pretty much a mirror-image of the goofy red-head's. Then you catch your reflection in what little chrome remains on the minibike's headlight. You are the boy's identical twin!
"Come on, Ty!" Your 'brother' looks anxious. "If anyone can get it going, you can!"
One of the younger kids grins. "Yeah! You can can jump over the big ditch like Evel Kneivel! Or those guys on Dukes of Hazzard!"
Somehow, you don't think they are talking about the new movie. You look at a parked car and see the year on the license plate. 1972!
