I have plenty crashing stories, though I can only be bothered with a few.
First one happened last year, I think, or this year.
I was riding down into a quarry with a few friends. To get down we had to ride down a very long, steep dirt hill, with a big ditch running all the way down on the right side, caused by running water I reckon.
so, I was riding down the hill at about 35kmh, then I noticed I was getting very close to the ditch. I tried to turn to the left, but turning too hard would cause me to crash, so I continued on going into the ditch, hoping everything would turn out fine. I was in the ditch for a bit doing fine, then I must've hit a little hole, because all of a sudden I was sliding out sideways, I slipped with the bike still "on" me. I slid for about 10m on dirt, mud and wet grass. When I stopped, I was about 2ft from a big concrete drain pipe. Phew
Another story is when I was skateboarding. I tried sorta slde down a kicker, but the coping was a bit big, my trucks rear trucks hooked up, which sent me flying head first to the ground from about a 2m height.
I woke up on the ground, last thing I remember was flying to the ground then blacking out.
Another one wasn't the usual crash.
I was messing with a shopping trolley(Some of you may have seen my thread with the cool gash).
Basically, I slipped, sending my leg into a sharp metal corner. Blood shot out, I laughed, went home, told mum about the accident, then went to the doctors.
I can't really remember any other significant ones.
