One thing you will always find, true horse people are true horse people. I mean, I've moved 6 hours south of where I used to live. I thought this was a non horsey area because like.. theres no major public riding stables anywhere in an hours drive of here. Anyway, at work one day, this older man noticed (and recognized) my boots and asked if I ride horses, because, hey, they're horse boots! Well, hell yes I ride, but not now because I can't find horsey people! We got to talking, and he gave me his wifes number because she trail rides weekly with a group of ladies and between him and her they have like 6 horses. He can't ride anymore due to injury so invited me to exercise and put miles on their horses for them. Wow, he doesn't even know me and just invited me to ride his horses. I called his wife and stopped by one afternoon after work; she handed me a halter and described one of her horses she wished to see me interact with, and I was on my own. She kept an eye on me, but I just walked up to this mare, caught her with real ease (yay hay piles), brought her out to an open area, and lunged her, worked with her a little bit. Then I got to ride her. I mean, this lady didn't know me, but gave me free rein with one of her horses, let me ride her the first day, and we've been buddies since. I trail ride every week with her and her group if I can, and stop by on days I leave work early to ride for exercise.
Like I said, horse people are horse people, it's something easily bonded over, even between complete strangers. If you keep at it, and leave yourself open, you will find the connections you are looking for.
