We used to sit on our rollerskates (then two can have as much fun as one!) and ride down the hills we lived on. This is one http://tinyurl.com/qu3858
I burned the wheels on those skates down to nothing. It's a wonder we didn't catch on fire from the sparks. THis hill I would ride up and down. Now, no way I'd go down it but I may try to bike up it. Though the bricks are not helpful. Used to sit in my wagon (which really, zero control of that thing) and go down the hills too. Man, I was a kid without fear (or brains, one could argue). And clearly I had a much smaller butt, since now I think I'd lose a rollerskate there if I tried to sit on it and ride down a hill!
