I'll eat just about anything, I just know people who won't eat Venison or elk. I don't know why, but I guess they are people who are unwilling to try something different.
My wife was like that, but since she's tried Bison, she has had a change of heart. I think it has to do with the factory farms and all the crap put in the meat. Michael Pollan's books have helped broaden her diet.
