Figured out not to put a helmet on the foot peg anymore when I melted the strap on the exhaust.
Anyways, I will never leave my helmet unattended anymore. 3 years ago when I was living in Phoenix I came out to a wet helmet. I didn't know it was wet until I put it on. After a few minutes on my head, I figured out what it was. Piss!
Last year I locked my fiance's helmet on my bike for about an hour. Came out and the straps had been cut and the helmet stolen. That proved to be a challenge to get her back home that night.
