When I was about 12 I went down this massive driveway of an abandoned building which was an about 35 degree incline.
I went down, got INSANELY FAST and unable to turn. I reached the end of the driveway, which T'd out ofc, but I was going so fast I just flew through, hit the curb on the other side of the street and got launched downhill, hitting fair sized rocks, until slamming into a Saguaro. I was in such intense pain I probably would've flipped the off switch if that were an option.
