I've seen maybe one or two guys on a Harley wearing a full-face helmet. 98 percent of the rest of them don't wear anything, I'd say about 75 percent don't even wear a helmet. This is Florida, though. Not wearing helmets is common. Another thing I see alot are kids (young college-age) riding sportbikes. They have the helmet but they are wearing shorts, sneakers. It looks to me like they spent all their money on the bike and not gear. This is even when it's in the 70's or low 80's out and you could wear some stuff at least and not get seriously hot. Maybe as often as I see a guy on a Harley actually wearing a helmet (not all that often), I'll see the guy on the sportbike that is "too cool" for a helmet and often is wearing shorts. These guys look really out of place, like they are oblivious to what they are doing, even worse than the Harley guys.
