Wear your Helmet! Safety is a measure of chance over necessity. Sure you may feel safe without it, but I would hate to learn this lesson the hard way. When you weigh the pros(safety) vs the cons(comfort) well let's say I would hate to forget it when I need it.
Relative to this topic is skiing\boarding. I grew up safety free when it came to helmets, but a couple of close calls following, shall I say creative trails has me wondering. So back to the tip. I guess the moral is...you only have one brain.
