There was this one time, at band camp...
One time, I drove my car down the hallway of my highschool. Left black tire marks where I spun out the tires. Inside hallway, btw. Drove through some maintenance doors that were designed to let a mowing tractor into the courtyard.
Lesse, I once jumped my car off a hill in Eugene Oregon (near 40th & Donald, that should sound familiar to anyone who's lived there) at about 70mph. Was airborn for at least two seconds. Might not sound like a lot, but count it off out loud. Surprised I didn't die.
I built a flamethrower, the one on my webpage, but that's one of those things that OTHER people seem to think is crazier then I do.
