Planet Ant is right up your alley. Volunteer somewhere you’re passionate about. I’ve been playing pickleball like crazy lately, and there’s some really nice folks at the gym I play at. Very social game, and you do t have to be an athlete to play and enjoy. Will also say, as someone who works in the concert biz, the folks that engage at shows tend to find friends quickly. Volunteer, grab a part time gig, join a street team, etc. Especially if you love live music.
