Probably no more risk in riding than anything else. Just that now, in the instant information age, it's easier to hear bout such things happening. I'd be willing to guess, that in most instances, the rider wasn't wearing proper riding gear, good fitting and in good repair too. Or they were doing something stupid. Or drinking. Or on a new ride unfamiliar with them. Blah, Blah, Blah.
I say it's been more dangerous for me to be sleeping in my Lazy Boy on a Sunday afternoon, than I've ever had dirt bike riding. (Surely everyone knows the story by now about that)
Use common sense in all things and you will be doing all you can to live a long life. It's not just about survival you know. And you aren't gonna cheat death either. Sooner or later, it's curtains. My good friend is in the hospital with six broken ribs and a split skull from falling off a 6' ladder while pruning a tree. I'm just saying, you never know when or where, so enjoy life and make it count for something!!

Troy's brain was shoved back in, and stapled shut. Bad photo, but those are steel staples there. It took about 30 or so to close him back up.

Me, Troy (In Bed) and Barry, my general contractor. Besides being one of my best friends, Troy works for Barry and built much of my new house.
