This unnamed, unattended park is one block south of US Highway 12, on 1st Ave. W, behind a Napa Auto Parts store and across 1st Ave. W from the Grand River Museum. There are no signs and it does not appear to be listed in any business directories. I found it only after local inquiry. No contact information was posted at the site. Payment is apparently on the honor system, with a locked wooden box for deposit of cash or checks. This is a classic any-port-in-a-storm overnight, a small gravel parking lot with hookups and a little bit of grass. It was the only RV park adjacent to Highway 12 that I could find anywhere along the 98 mile stretch of Highway 12 between Mobridge and Lemmon. We camped here in a Motorhome.
