Re: If you could be air-dropped to fish anywhere in America....
I'd have to agree with stenacron's choice above of the Wind River range... I've done a couple backpacking trips on the Reservation land and the air drop sure would make getting into the lakes a ton easier!
If all of North America is included, I think the choice would have to be somewhere in Labrador or Quebec for giant brookies, or the far north for Arctic Char.
Oh yeah... there's Alaska for big, aggressive rainbows...
