$1K a month for rent is ridiculous! I wonder what the area campgrounds are getting per month?
On
www.campgroundreviews.com the Bismark KOA is listed at $41 per night and Hillcrest Acres Campground is listed at $22 per night but the poster complained "... The only problem is the seasonal workers are all segregated to the rear and they must travel past your site early in the morning to go to work... " darn those pesky workers! Their monthly rate is $380 for 30 amp service. So that's not too bad... except there are a total of 3 campgrounds (1 is public) listed for Bismark. So I bet they stay full on their long term sites.
Sometimes you just gotta do what you gotta do!
