I was hitting a jump in the when a little kid cut across the landing so instead of landing on him a tried to stop/ turn but l didnt have enough time so l ended up just missing the kid but landing on my shoulder. The kid just skied off didnt even notice.
hit a booter, landed a little front seat / sideways and dug my downhill edge in and flopped my head off the ground. it was violent enough to crack my helmet open. needless to say, i was scrambled eggs for a while, and had post concussive symptoms for months. shit's scary..
another bad one was when i was boarding years ago. 270 on to frontside board to hard bail, which broke my shoulder. i still get pain in it when i move my arm into a certain position (if it's forced into external rotation, like when someone twists your arms and yanks them behind your back). no fun. feels like i've got a nail being hammered right into the shoulder joint
Tried something off a small jump (maybe a 5? I dont remember anything about that day so...), and my theory is that I caught my edge on the last 90 degrees of rotation and smashed my head down. I was unconscienous for about 2 minutes apparently.
