Came here in May 2020, making a mad dash to WA to hunker down for the summer.  We booked a night here because of it being a Passport America Park and at the right location for our route.  For $20 we got a pull through that was level enough, gravel and full hookups.  We did not use their bathrooms, but they have them.  Mostly occupied by local workers, clean enough but some junk hanging around.  Owner on site and nice enough and for the price it was just fine.  There are about 5 or so pull through sites that are super easy to get into and out of for an easy one night stay.  It is on the Powder River, but not much of a scenic spot.  Has good free wifi, we got a decent Verizon signal here, too.  I wouldn’t make an effort to come here again, but if it works in our route and a one night stay I would do it again.
