You know while driving around now, the first thing I notice when I see other riders is what they are wearing. Most notably, are they wearing a helmet.
While I was practicing today another rider came over to me on a sport bike as well. What struck me, however, was that he was wearing a tank top, thin shorts, and flip-flops. He was wearing a helmet though.
He had a learner's permit, didn't know anything about the MSF course, and didn't seem to have any intentions of getting his license anytime soon.
