If traveling US-2 in Montana, consider a night at Trafton Park in Malta. Camping is $3, honor system. Park anywhere you like, there are no set campsites. Nice big cottonwood trees throughout the park. There are rest rooms and I recall at least one water spigot. A small river borders the park on the north, and fishing is allowed. When I was there about 5 years ago, they were having a local calf-roping contest at the corral right next to the CG and I watched and took pictures. Other than that it was peaceful, and only 2 other campers besides myself. Plenty of room! Turn north at the rest stop and it's just a block north. It's very informal and doesn't look like a CG, it looks like a town park, but don't be fooled...sure enough, you can camp there. If you like to camp where you feel as if you escaped civilization, you will like this place.
