This is not a campground as you might imagine. There are 12 pull through full hookup sites across the road from a well stocked hardware store (under the water tower) and that's where you check in at the hardware store cash register.
Just park on the side of the road before you get to the store. This is a safe place to stay for one night if traveling I-70. It's about a mile from the interstate and no traffic noise. Sites are gravel and fairly level. There are no restrooms, showers, trash cans or laundromat, but directly across the road you'll find a convenience/ liquor store, a laundromat, car wash, and a pet wash. Everything you need for an overnight rest.
When you are done checking in at the hardware store the clerk will give you a couple of tokens to light up the fire breathing dragon next to the camp sites. Light him up when it's dark for the best pictures. Each token gets you 10 seconds of flame!
