I don't do many flea markets but I can't resist Rogers Flea market in Ohio. I still get better finds on cold-call picks but I generally find some items of equal or greater interest at the flea market but with a heavier price tag.
It just so happens a couple guys are starting a TV series based on the Rogers Community Auction and Flea Market.
I was there when they were doing some foundation work and decided to check things out.
Here's a video promo they made among others. A brief comedy moment at the 3:24 mark.
First episode is August 2018.
