My friend, had belonged to LoW - Loners on Wheels. She really enjoyed camping with them. They have a place in Bushnell FL where a group of them winter. They also have a Ranch or something out in Deming NM. I think they have regional chapters who have local campouts once a month.
It worked out well for her. When she first retired (Nov) and went full time, she went to the Ranch in Deming, NM. Was not long and she had a massive heart attack and had by-pass surgery. The folks there at the Ranch were wonderful with helping her during her recovery. Me being in PA, with a friend in NM - well, it lets you feel pretty helpless as far as helping the friend.
Before she went full time, she met a lady friend who lived in this general area. They used to go to some campouts and on some trips. They traveled together -followed each other and had walkie talkies. I just thought it was safer for both of them, to be in a pair while on the road.
With belonging to that group, she really had friends just about anywhere who would look out after each other, if someone got in a pinch.
She particularly liked this group as they didn't allow any hanky panky. Not saying that folks didn't meet and eventually become a couple. But the basic theory behind the group was a place where single people could enjoy companionship, and like minded activities - conversation, pot luck meals, etc.... without being put in a position where they felt like the fifth wheel - the only single amongst mostly couples.
