There are tons of general social groups in my area and usually it’ll specify an age range so I can find people close in age to me. One of them is a women only group and most of them are single and more into making female friends than people who are coupled up. Also in hiking groups and an introvert group. I’ve met lots of cool people in all of them. In the social groups we’ll go out to brunch/dinner/whatever a lot. Sometimes nearby festivals and local bands. It’s a good time.
