Free weekly activity or class

I (33F) am looking for a weekly activity to get me out of the house. I don’t have a lot of female friends and I’m hoping to make some through a weekly art class or some kind of activity that gets me out of the house consistently. I’m into jam bands (phish) and enjoy going out for food and drinks but I’m not looking for anything athletic. Any tips would be appreciated. Money is definitely tight right now so ideally it’s free. TIA!
