I`ve camped at Interstate a few times now. There is a lot to see and do here, which is why I love it! The campground itself is definitely not as private as we like, however. There are a couple of more private sites, but they`re tough to get. They`re very strict about alcohol on the sites, so be very careful or you might get booted!
Overall, it`s a nice place to stay, but if you`re looking for more privacy, go to the Wisconsin campground!
