If you are looking for an interesting weekend place to go and camp try one or both of these:
In September there are two steam thresher's reunions in Minnesota and North Dakota. These are interesting events with lots of history to see. There are campgrounds on site at both places. I know New Rockford also has a local public campground with hookups & showers at a nearby park in addition to the one on site. Here are websites of info.
New Rockford, ND is Sept. 21,22,23.
Rollag Mn. is Aug. 31-Sept.3
