Hi Laineyjain,
.
While I can agree with the "people don't want to be outed" part, why don't you try the opposite in as subtle a manner as possible when talking with them?
.
For instance, I'm still in male mode at work and when I have to be around family. The only thing that I wear that could out me is a necklace on a long string (so it's easily hidden under my work shirt) with a transgender symbol on it. If I want someone to know, all I have to do is wear it over my shirt rather than under. I don't have to say a thing about being trans. Just say hi, or whatever friendly greeting I would normally use. That gives them the choice of whether or not to reach out to me, it doesn't out them so they don't feel threatened, and it's not verbally spoken about which may make some wary of strangers who may be listening.
.
In smaller/rural communitites, it can be a lot more difficult to meet people. As a community, trans people don't really have the sublte tells that parts of the gay community often uses, so I guess we have to improvise a little.
.
Anyway, that's my suggestion for what it's worth. Good luck with meeting people around your area.
