In addition, if you do not have a helmet on, people will know you are not a cool in-line skater. In fact, you will look like a rank amateur. People will laught at you, and not only behind your back! They will ride right up to you on their bicycles and laugh RIGHT IN YOUR FACE. I've seen it, I was there! I witnessed the Great 1993 Face Laugh performed at Daytona. Right in front of hundreds of people, there it was. There was nothing the poor skater could do but take it. Nowhere to run, no one to turn to. THIS COULD HAPPEN TO YOU! Beware.
