Final Approach
Ouch!!!Yes. I was screwing around in a grassy field behind one of the motocross tracks one time and hit a hole going ~65. Threw me over the bars and I went head first into the ground. Everything went black for a minute, but I was fine. Still raced that day. The other times were just typical falls (ladders, ramps, etc) for the most part

If it were me, I would want to be checked for concussion after something like that... at the very least. Glad you were okay though.
(Look up Natasha Richardson for a scary example of what can happen when someone thinks they are "just fine" after a head injury.
