I haven't been in a few years but I use to love to go. They didn't really have concerts back when I was going but I think thats changed. They did always have a big warehouse basically filled with arts/crafts/plants that people would compete for best in show and I enjoyed looking at all of that. No rodeo either but we did have a pretty big petting zoo and all the 4H kids had animals and stuff. Also pig races.
I would like to go and see if any of the food concessions are selling anything spicified too.
-edit- actually now that I think about it I think they did do a small rodeo or at least horse racing, I was just never there when it was going on.
