I've been a member of a number of juggling clubs over the years. If you're not into juggling, I'm sure there are other kinds of clubs around, but if you're a juggler or juggling-curious, they're great. They tend to be super open to new folks, whether they can juggle or not. Often folks would go out to eat afterward [depending on the time of the club meeting]; at one club they even had a weekly movie outing afterward for a long time.

The larger juggling community is great too--there are little festivals and larger conventions all over the world, with great shows but also great social scenes.

I met my spouse at a university juggling club. Neither of us attended the university, but we were both club members, as were lots of our friends [after a while, anyway].
