We have the Great Wisconsin Cheese Festival each year. It's basically a swarming area for tourists and carnys and few people from in town even bother to fight the crowds. It takes place in the beginning of June and afterward the park its held at is completely trashed for the rest of the year. The tents turn the grass to mud and it looks trampled. It's right along a chanel of the river that is a dumping ground for cups, paper plates, stupid toys won at the games, and carnival goldfish. Thankfully its our only large carnival.
We also have Kermis dutch fest which is a village heritage festival. Much more controlled and fun for in-towners.
