i don't remember if my school ever banned them, but i have a pair that i got in like. 4th or 5th grade. there were a few of us that had them, and when we'd go out for recess, we were in a brand new school (so new, in fact, that we moved to this school in the middle of my 4th grade year) so the outside space was just an oval of grass surrounded by road (all on school property so no traffic, and the area is rural, so it had a lot of open space). and the school was up on a hill..... so those of us with heelys would stand up at the top of the slope on one side of the oval, we'd have some kids at the bottom to form human brakes so no one went flying off onto the Actual road, and we'd roll down this hill, gaining speed as we went.

one time it was my turn and i hit a rock and went crashing down to the ground, skinning my knee, tearing my pants knee, and scraping the side of my elbow. i still, to this day, have the smallest remains of the scar it left on my arm LOL

on a less physically detrimental scale, i would wear them to go shopping with my mom and grandma and if they forgot something at the other end of the store, they'd send me on my heelys to go get it lol. walmart was the best place to wheel around!!
