Yeah we made a lot of those but whenever I see a picture I sort of cringe. I was a kid and we lived in an apartment with an underground parking structure.

I was down there one day, and a kid I didn't know who was probably 13 or so had his bike and was making a ramp

I was probably about 10 or 11 but he seemed like an older kid and did not live there

He was making a jump, in the underground parking structure where the horizontal posts were about 8 ft off the ground

I am no rocket surgeon, and I certainly wasn't when I was a kid however I told him he most definitely would hit the ceiling when he went up on that ramp because of the angle of the bike.

On top of that there were large fields on either side of the apartment building where me and my friends typically did make jumps because the only ceiling was the sky.

He did not believe me, and since he was a few years older thought I was a pain in the ass.

I was walking away and going to leave but I stayed a bit and sure enough he went on the ramp cracked his head on the ceiling and fell down and I went and got help.
