Seen the same thing up here. Dealer leaves boxes and buckets of tools outside. Watched a guy set up, and literally poured 5 gallons of rusty water mixed with tools onto the table. Made you want to gag, with all the insect carcasses in there. There was a flea market like yours, where the dealers could leave things sit from month to month. Not much, or no cover, rust all over, and they couldn't understand why sales were down. We do get some rain in Nebraska.
