We stayed here as we blitzed across the country (16 hour days!!) This was the perfect flat spot right off of the highway for us to pull in, open our roof top tent, eat some freeze dried food and go to bed. 

There is a 24/7 security guard who takes you to your site (Security and maybe because one could easily get lost?) Showers and restrooms are located throughout the campground. 

Truthfully, we were only there for maybe 8 hours before we got back in the car and took off again. I would definitely stay again in our larger trailer if we find ourselves in the area because of it's location to St. Louis it's a clear draw for those who want to visit the city and stay... not in the city.
