Club Ideas?

I've used clubs mainly to keep families together. In one save I was playing a pair of siblings, and when they both got married and settled down, I created a Sibling Revelry club for the siblings (and their spouses) to go out on the town (bowling, pub games, restaurant dining, etc.) and for their kids I did Cousins and Such. I've also done a Chess Club -- they meet at my Art and Science Museum (set as Art Center) and play chess (naturally). I'm also thinking of doing four kids clubs that all meet on the same lot, each one focusing on the four children's aspirations, so a Whiz Kids club that would do things like chess and the science center, a social club that would talk to each other and use the puppet theater, an creativity club with activity tables, toy box, etc. then an Activity club that plays on the play equipment and with the video game platforms. Haven't decided how to set up the relationships -- maybe the Whiz Kids are nice to the creatives and mean to the other two or whatever.
