Well, since the helmet law was repealed last year, the majority of the people I see riding without helmets are riding cruisers or touring bikes. There are quite a few sportbikers as well, but the majority seems to be the wind in my face, and my sunglasses will protect me types. When I was younger and much dumber and living in Los Angeles, I wore my helmet 75% of the time. Now that number is 100%. Helmets are cool, spilled brains..........uncool.
