I love the Missouri state parks they are kept up and clean restrooms. The hosts have always been friendly and helpful.
I have stayed at Sam a baker in a tent.
Arrow rock in a pop up
Meramec
In Troy Missouri at CUIVRE river
I have stayed at KOA on Route 66. I would not recommend at all, train runs through at night and very narrow sites.
I currently keep my camper at lost valley lake resort, it is private and I love it.

I go camping with my family of five and two dogs.
