go tray surfing.
More about go tray surfing.
(used to do this alot back in my High School days. I grew up in a little hick town, what do you expect?)
Basically you just get yourself a fast food meal tray, hang onto a friends car and have them drive around.
I'd suggest you start out a little slow, and work up speed....and try to stay in a straight path.
It can be quite a good time, if you don't get yourself hurt. Even if you do....what's a few booboo's compared to immortality on film, right?
