I used to make fun of the quad guys quite a bit, Then one of them showed me his prosthetic leg 
Well my brother-in-law Terry rides bikes with a prosthetic leg. Every time they come visit from Alabama he looks forward to coming to our house because he knows I'll let him take one of my bikes out for a spin. It's his left leg and he just lifts his whole leg (fake foot doesn't really bend much) to shift up. He doesn't even remember having two legs, we was born with some kind of deformity and they had to amputate right under the knee at a very young age.
Sorry for getting off topic. I just really like Terry and I think it's awesome he rides so I brag him up any chance I get... 
Cool story Coop.
I was making fun of this guy's couch, and he showed me the prosthetic, I turned red and then we had a good laugh.
He lost his lower right leg in a street bike crash, Still rides street bikes but says he has trouble in technical sections on a dirt bike.
Dude also said he rides with mostly dirt bike guys caus he don't like quads
