What is the best flea market you have seen or known about in the u.s.a.?

Answer 1

There's one that's held on the East side of the Mississippi River through many towns up and down the highway that borders it in Wisconsin. I don't know when it's held or the name of it.

This is what I was thinking of, the 85 mile sale. Also type in Great River Road sales for more. But check Lake City, Mn on the site I pasted.
