The most different thing- Oryx. You have to win a lottery to get one in White Sands (or go to Africa).
Also ate ostrich in Oklahoma but not very impressed with it. Venison often, cow tongue once at a friends house. I like chicken livers. I like to try plants I haven’t tried before. The Indians used dwarf cornel in pemmican but it tastes so bland its not worth it. Chewing on a wintergreen leaf is good.
