I recall but it was years ago now, that there was a section where AARP members could post personals type ads. But as I say, that was long ago. I've been a member since 2006 and it seems to me like it was probably around that time that I was feeling especially single. I do know that there are a LOT of women here on the site but they aren't categorized by any geographical or age dynamics that I have seen. But most of them seem friendly. You could always just say hello and see if it leads anywhere. For me the window shopping and flirting is the best part!
Good luck, I hope you find a keeper or, better still, I hope someone finds you to be a keeper!

It's nice to be important but it's more important to be nice.
