I don't know who runs the flea market now but several years ago I believe Ken Riland parked the vehicles and it was done right and organized. The top lot was completely full and then the bottom lot was used. Some of the problem is that people don't know there are sellers in the farm shows main lot.
What they need to do is put a form on the internet, have sellers print it out and send in a check for their spot(s). For example, there is 150 spots, the first 150 spots paid for get a spot. When people send in their form, make sure they have their name and the size of their hauler that way you can have a parking grid all ready for when people get there.
Beerhill, bottoms up!!!!
