There is little to no queer or trans community in San Mateo County. It's like there's nothing between San Francisco and San Jose.
I started with Google, looking for peers/resource in my area. I found precious little, but some are there. Being a member of a church where queer and trans persons are openly welcomed helps. Through mutual Facebook friends, I've been finding more things near me. I went to a bar for the first time at age 42 last November. I've been to a couple of others since then, but felt like I was out of my element. Rainbow Skate was better and definitely trans-friendly, but I'm 1 of a very small number there.
The only peer group I have at this point is the Transgender Parents group up in SF. People are in various stages of transistion there (pre-op like me, post op, pre-HRT). While many of the parents there are my age, I have the oldest kids. So, I don't quite fit into the group.
I'd like to find something closer to home. I guess I could try to start a meetup or something, but I'm not sure how to proceed.
That said, I feel like I've been granted peer status among many of the cis-women I know. It's like they've welcomed me into their circles. But, the struggles that cis-women face aren't the same as what I face as a trans-woman. A peer group would be ideal, I think.
