Here is a new casino for you to add in the Upper Peninsula of Michigan: Kewadin Casino, Christmas, Michigan. It's about 3.5 miles west of Munising, Michigan.
There are 8 FREE 50/30amp electrical posts in the back of the west lot (see photo). The spaces are short, only about 20 ft. However, there are a couple of spaces where you can hang over into the dirt lot behind. And a couple of spaces where this will not work because of the trees. This is a small lot and there is highway noise very close. In Munising, the boat tour to Pictured Rock National Lakeshore is interesting.
