Hello, I'm new to this site, this being my first post. We just moved from a Pop-up camper to a TT. We are planning on going from Missouri up through South Dakota and across through Wyoming. We are from the Kansas City Area. The campground we are going to spend most of our time in is the Yellowstone Valley Inn. It seems relatively close to the East Entrance of the park and looks nice in the pictures. Does anyone have any idea about this RV Park. I really wanted to stay in Yellowstone at Fishing Bridge but with no electricity the last thing I want to listen to all day is generator's running(and I don't have one yet). Does anyone have any recommendations of where to stay along I-90 through South Dakota while we travel up there. We're planning on taking 3 days to get there. Any suggestions would be much appreciated. Thanks! Matt
