Any advice on finding friends around here?

I’m a woman in my 30s so naturally my friend circle slowly disappeared as people started having kids. I have no children and so a lot of my free time is spent on random hobbies (painting, biking, going to local shows, running, currently trying to learn how to slack line, etc.) I’m fairly introverted but have been wanting to find some fellow artsy, misfit types (or any types, whatever). Any advice/any good groups to join to meet people?
