Hmm im lucky enough to not have had to many bad accidents but ill share one.
When I was about 9, I went out with some friends to the local park and there was older boys from around town there, the local council had just dropped a massive amount of Chip Bark to fill the park, and one of the locals had managed to bring his massive Skateboard Ramp from home and set it up in front of the Chip Bark to jump bikes into.
After watching for a while, somebody asked me if I wanted to have a go at it, I stupidly agreed obviously.
Long story short, I jumped the Skateboard Ramp, allmost knocked myself out on a branch in the air, landed in the Chip Bark safely ( Atleast I thought I landed safely) walked away and then felt a pain in my leg.
Sat down to investigate what the pain in the back of my leg was, I rolled up my pants and saw the red tissue of my thigh hanging out of my leg -.- which is when the tears started to flood out due to shock.
Turns out when I landed in the Chip Bark awkwardly my bike handle and pierced my leg...... lol, got rushed to the hospital, got 12 stitches and was couch bound for a week or two
