How do you guys find other like minded outdoorsy people?

I’ll start by saying, I have amazing friends who generally like the outdoors a lot, however, my interest is in winter backpacking and mountaineering and unfortunately, many of my friends just aren’t into those things as much as I am. That’s fine by me I don’t ever feel annoyed if my friends can’t accompany me to some things however, it would be nice to not always have to go alone on some trips. My question is, how tf do you guys find people as crazy as you???
