Take that knife out of my belly!! You're callin' me KPaul? I'm the anti KPaul (well, assistant really since Longrider is the real anti KPaul)
Anyhoo, I'm not commenting on the usefulness of helmet laws, merely reporting the facts.
I wear my helmet when commuting on my sports bike, I tend not to wear my helmet when putting around the mountains on my cruiser.
