Beef is good, but Buffalo is better. I think it tastes better, plus it's healthier than beef.
There's a buffalo farm just down the road from the airport where they do everything from raise the buffalo to slaughtering and selling them. And for all the anti-big business hippies, it supports a local family business, rather than those large multi-national soy conglomerates (ok, I realize that's a bit of an exageration, but still where can you find a family made soy-burger or Tofurkey?).
I'll second the venison comments. A buddy of mine makes his own venison sausages which are absolutely amazing.
Check out the book "Omnivore's Dilemma" as well as the documentary "King Corn". Both are really interesting looks at corn and the food industry in America.
