I first had them in So Dak in the 1960s. Lots of ranches now grow bison especially in the Great Plains of Wy, MT, Neb, the Dakotas. I can get ground buffalo meat at several grocery stores in Nevada. I can get lots of other cuts with a little looking.
I served buffalo roasts for Thanksgiving for about 15 years in a row. Bison meat is leaner than beef with less cholesterol. It has a nice flavor. It is best cooked slowly with moisture and is perfect in a Dutch. I like to use beer, apple cider or wine to cook it in with plenty of seasoning. I like to make barbecue sauce from scratch using some strong coffee as a base. It makes me hungry just writing this.
