Chupps has its auctions the first Saturday of EVERY month. The poultry is placed under a roof, though the sides are open, so there's quite a bit of protection. They have a concession stand that sells food and hot coffee--not sure what all. There are also other vendor booths selling quite a number of things.
The auction itself takes up most of TEN acres, and you can find almost anything you could possibly want. When you get near, you'll notice heavy traffic; mostly trucks with trailers, coming from both directions. It is on the righthand side of the road if you're going toward Chouteau. You'll also see several acres of parked vehicles.
