Just curious because I see nothing but riders in my area without a jacket while riding. I simply think its plain careless not to ride without protection, unless you like have you skin peeled off. Even with the weather I always think to myself...what if? I've done it twice now and I was already super paranoid and I never think I'll do it again. Those that always where a jacket, did you always feel that way or did you learn the hard way? Those that don't always wear their jackets, why?
