Something I've wondered is why people don't turn abandoned big-box stores (and smaller malls) into flea markets. There wouldn't be any problems with the weather. The merchants can rent by the month and not have to tear-down their shops on Sunday evenings. Bathrooms would be available. Power could be run.
Flea markets are an eyesore and typically sell low quality merch, attracting ebay type resellers slinging phone cases, gold by the inch, stuff like that
But setting up an indoor flea market means they wouldn't be an eyesore, and would put a property to productive use that would otherwise sit empty, generating no tax revenue, possibly becoming a target for vagrants, arsonists, and graffiti taggers.
