There are some very large flea markets in the US, but they tend to be in small towns, and the plethora of small ones make it difficult to search for the large ones.
I want to plan a trip visiting some of the large ones.
I am looking for a listing of flea markets that are destination events. I know about these two.
Brimfield Flea Markets, Brimfield MA ~ Not sure of actual vendor count, but it's a couple thousand at least.
Rodgers Ohio ~1,600 Vendor spots attendance varies
While The Elephant Trunk is popular it maxes at about 500 vendors and is not in the scope of this question.
Edit updating parameters for the question
Not every state, has a flea market with 1,000+ vendor spaces. Additionally on researching I am finding several indoor markets advertising themselves as "flea markets" while those have value for the local, they are not destination events.
Looking for the largest outdoor flea markets in each state. Vendor spaces are rented for the day or the weekend. You park in a single place and walk between the vendors as opposed to a highway yard sale like the 690 mile 127 yard sale
