activities for post-grads?

just graduated from uw and now live/work in madison. looking for activities where i can meet other under-30’s so i’m not just hanging out with my friends still in school at like… chaser’s 2.0 lol

i just joined a work out group but would also love to join other clubs/groups/classes (maybe cooking, crafting, book club??).. literally anything i can do once a week so i can meet people and also have something to do T_T free would be nice but i’m also willing to pay a little bit if it’s going to get me out of the house !
