We live in the south and spend our summers in the north. Until last year, we had a Class C Motorhome that we'd spend all summer at the same campground which has probably about 75% seasonal. We have been in the same site for the last 3 years. Most of the campers are very friendly and our neighbors are great. We've become good friends with several of them even if they are old enough to be our parents. Some have grand kids the same age as our kids.
Last year we traded the Motorhome in for a Destination Trailer. It is amazing how many more people we met as a result. People that never more than waved to us as they passed, would actually stop and chat with us. Even away from our site, they'd see us and talk, at first about the new TT and then just about whatever.
