My local library has many events for essentially every interest known to man and all for free. Its fun going to random meetings to have a blast and meet people. Its how I picked up knitting even though I thought I wouldn’t like it.

Photography clubs, chess, math, many many reading groups, yoga, business meetings, entry CS meetings, board games, web design club, various seminars, coffee hours, activism meetings, and so much more.
