We have a small one and it will run until thanksgiving, it moves inside when the weather gets rough. Now it is under some high carport type metal structures. There have been only 10 or so vendors as most of the produce is wrapping up. Everything needs to be grown or produced by them in the county I believe is what the one guy told me. Usually some sausage makers and occasionally a cheese maker, a few farmers with meat, some bakers.
Hope you brought home some good cider and apple butter.
