Please wear one. I know what I am talking about. I lost my youngest brother to a motorcycle accident. He was not wearing a helmet. They said that had he been wearing one, he would not have had injuries THAT serious.
Making the wearing of helmets voluntary? I'd rather be sweating than potentially suffering a fatal head injury. That's what helmets were designed for. The amount of people I see riding motorcycles without them just boggles my mind.
We were on I-64 the other day and a guy passed me going at least 90 MPH. I was set on cruise at about 75 and we were keeping up with traffic when this guy comes up on the side of us all. He was out of sight before we knew it. Idiot! No helmet and running fast. No leathers either.
