I remember when I bought my first motorcycle (1947 HD Knucklehead in a box). After I got it all put together and running, my Dad handed me a helmet and a toe tag. Said, "choose one". (Dad was not a subtle man, but he ALWAYS made his point)
I personally know 3 fellers that I used to drink with at the old Music Box that fugged up on motorcycles after drinking, without a helmet. 2 got buried, one went back to his home country with a broken pelvis and brain damage.
