I think I struck a chord with this thread. You all have been sooo supportive. Trudy, the RV commune is an interesting idea ... but I don't play well with others, tho' I do WORK well with others! LOL.
My experience traveling alone as a single woman has not been an isolated one. My camp-host experience has taught me how to go out and talk to other campers. I ask questions, "Are you headed out ... or heading home?" THAT is a great conversation starter. I tell people I have rig envy (when I do), and I get the story of this rig plus the ones that came before. "Are you a full-timer?" No/Yes ... they tell me about their lives & travels and/or where they live. I try to meet their dogs & talk to the women first ... they tell me stories about their husbands behind their backs.
It's a lot of fun. Then I move on and talk to the next folks. The next time I walk my dogs, people smile & wave. I ask them about the fishing / boating / hike that they planned to do that day. BLAH BLAH BLAH. Uh oh. I think I would embarrass Martha.
My method of travel does include staying in one place for a several months at a time ... so I make a point of developing new friends. I do, however, have an "in" in any community I visit, because I am an AA member and there are always rooms full of people who already love me -- they just don't know it yet!
I get lots of hugs & my dearest friends in my travels usually come from that source.
I DO notice that no one flirts with me when I'm on the road ... except that I get hit on by women. What does that say about how appealing strong, independent women are to men?
