I've never been to one myself either (yet)
There's a university one here but I never got round to going as I was depressed when I heard about it and have loads of work to do now I'm better
This one I'm gonna go to does things like going to the pub, drama groups, walks, visits to places etc. They do a week at one of the centerparks places as well. So it's more of an active thing than just the usual support groups people go to. That's why I'm interested in it as I've been trying to get out more and meet people more over the last year, but it's difficult to keep up with most NTs so I've been limited to only things I can do/places I can go on my own.
It's called Aspirations (maybe spellt differently though) if you wanna have a look into it. This one is a mnanchester group but there may be others, and it does say people from outside the manchester area can come to most.
The info they sent me is downstairs but I'll find out when it is and let you know incase you decide to come along.
