Massachusetts has a little bit of that as well, though in my experience, it only really means that the tribe members have more relaxed rules around regulated hunting/fishing seasons. Being able to fish out of season and harvest in closed shellfish beds, that sort of thing.
I farmed them for a number of years and they are surprisingly versatile. For the most part they taste like your standard manila, its just got a lot of mass compared to most shellfish. Preparation is everything and overcooking gets you a rubbery mass which isn't so great.
I enjoyed slicing the siphon and deep frying them, but at that point it was less flavor than texture what with the beer batter and all, etc.
Was going to bring up pow wows. Great way to find Native foods, learn about culture and history, and for many, most of the proceeds go back into the tribes hosting the event.
There's a joint in a little New Mexico Town that has amazing frybread. I wish I could remember where. It was somewhere I stopped on a whim on the way through.
