Its an old car booster safety seat, duct taped (at-a-gurl) to Katie's scooter. This contraption had been in the works for a few days. I guess you could say I wasn't impressed with the initial prototype. The real innovation came when they decided to add 2x4's (bungee corded to the seat of course) to the sled as leg supports/footpegs. The result is a screamin' fast thrill machine. Watch out Super Dave, we're comin' for ya.
Sorry, if its blurry, she was just so smokin' fast.
Allie is aerodynamic, already being low to the ground - that's just how she rolls.
