Rum River State Forest

No potable water, grey dump, nor trash cans, but it's rugged wilderness along a gravel road with plenty of space to park.

Most of these spots are cutoffs on the sides of the dirt road. They are deep and have plenty of room, though. Almost all of them I could see have firepits. The spot I stayed in was the most secluded I could find. It was through a ditch and up a small hill and set back in the woods. There is a firepit up there as well. I spent 3 days here with only one car passing through on the first night. After that, nothing! You wouldn't have a problem finding a place if your pulling a trailer.
