> Never say never, but usually advice from the ignorant is not worth much.

Differentiate between the ignorant and the inexperienced. That's what I'm talking about here. That's what I find so incredibly insulting. People assume that inexperience IS ignorance, and it's not. It's really weird that you're taking this position after starting the thread.

> As far as I know, nobody has ever even tried to jump Grand Canyon on a motorcycle.

Evel Knievel tried, but he couldn't get permission from the government. So he bought a piece of property at the Snake River Canyon (which is as wide as the piece of the Grand Canyon he would have presumably jumped, had he gotten permission) and jumped that instead. He broke his collarbone and three of his four limbs.

But that was the Snake River Canyon, and, hey, it wasn't me that did it, so what do I know? Maybe jumping canyons on motorcycles is safe after all!
