After reading his second negative post I decided to review some of his earlier posts. His 5/30/2013 post is kinda interesting
"If I were you I would pass on campground memberships. There are so many options for camping why restrict yourselves to private membership campgrounds. We much prefer public (state parks, national parks, national forests, Corps of Engineer, and sometimes county/city park campgrounds). They are more natural and generally lower costs. The national pass would be a good idea. Many states do sell annual passes but may not pay, depending on how many parks in that state you would visit and whether or not entrance is included in the price of camping. "
So what really turned him against Michigan state parks? I've used them for years, and they are great places!
