I’m sure this issues has been covered, but I was recently visiting Colorado, where I was born and raised, and I was shocked at how few motorcyclists wear helmets.  Colorado had a helmet law, until it was repealed in 1977 under pressure from a group, ironically called Colorado Motorcycle Safety Association.  I would guess that less than 20% of motorcyclists I saw had helmets, or proper riding gear for that matter.  The few helmeted cyclists I saw, mostly on sport bikes, were wearing t-shirts and shorts.  Virtually every cruiser rider, and passenger, was un-helmeted.
So here is the question – if you live in a state without a helmet law, do you wear a helmet, or, if you live in a state with a helmet law, would you lose the helmet were the law repealed?  I understand that helmets can be annoying, but I can’t fathom risking having my head crunched, maybe I’ve seen too many motorcycle accidents.
