KEK!! Saved!
Binney & his pals are fantastic. Love 'em.
My understanding is that he has lost a portion of one leg; he has a prosthetic but hates the way it feels (can't blame him there) and uses a cane when he has on the prosthetic, but probably uses a chair when that's more comfortable/convenient.
"A Good American" is a great intro to Bill Binney. Should have been called "Great American", though :)
