> hiking/being outdoors (when it isn’t freezing)

This may or may not be a good recommendation for you, and it doesn't help you right now since it is freezing, but disc golf is an extremely chill and welcoming sport and Druid Hill Park is a great place for a beginner to go try it out. It's basically just a nice walk through a park while occasionally stopping to throw a thing. It's very accessible for a new player...it's hard to be good at but unlike real golf it's not hard to get to a point where you don't completely suck. It's also free, other than the cost of a couple discs (and there's a decent chance someone would give you some old discs for free)

If you show up there pretty much anytime, I'm sure you'd be able to find a group that would take you under their wing and probably even let you borrow a few discs. Their big night is Thursday night, where a bunch of people show up and they have triples (they randomly assign people into groups of 3 based on skill level). I think they still do it in the winter but they start earlier and earlier because of sunlight.
