Dave, I am not familar with Indian Spring but Sue used to live in the area and says the last she heard (about 20 years ago) it was mostly motor homes and trailers, staying there permanently. Again, that was 20 years ago. They have spent a lot of money on a web page and cannot be that close to the big auction, to let it be run down. This area is not noted for its campgrounds.
I'm betting you have been there before. If so do you remember the field, used as a parking lot, that is south, across the road, from the auction. I have seen campers in there, during the auction.
The weather will be dry or wet or both. Either way, it will be hot.
Our mosquitos are first cousins to the B24s they fly in Michigan. Bring your antiaircraft guns.
