I've seen what it takes to put a small "crack" in a helmet. I can't even imagine what he had happen with that. That's a split helmet.
And remember. If you don't wear it right, don't wear it at all. Seriously. Make sure it's snug. This is what makes me mad. If you don't wanna wear a helmet, alright your choice. If you are wearing it wrong? You make me mad. You clearly want to be protected and must have reason, yet don't care enough to actually have it protect you....
Hoping he's back out soon.
Im all for having fun, showing your tits and getting fucked up on a river float but it can be done without being a pig.
