Yes, I ALWAYS wear my helmet when I ride. Of course, I just started riding in December, but much as I hate helmet hair, I always ride with my helmet on. When I was a kid, I didn't have one. Back then, it wasn't required, and we were lucky to share that one bike amongst the five of us (little bro had the infamous Big Wheel)!
I also wear a helmet when I scooter, too.
Hey, thanks,Pete, that was a really informative link. It scared the bejeezus out of me, though. Well, you know, I'm such a scaredy cat anyway...
