Is Socializing a Dying Thing in the RV Community?

Agree with the trend you noted. But not all is lost- there are still outgoing folks about.

What we do is just smile and say hello to folks walking by the campsite or when we are on our way to the bath house/etc. Sometimes a nice comment on their décor, Rv, dog, or whatever. Sometimes that starts a conversation and those are the folks I want to talk to anyway. The grumps can stay inside and isolated if they want.
