At one time there were lots of men's clubs in the US like the Elks and the Moose lodges. In the San Francisco area there were maybe a dozen active Elks lodges and they had a 3-cushion league. They seemed to represent a large fraction of the 3-cushion play in the area. The US 3-C Nationals were held several times at Elks lodges. Most of them have either gone away or greatly reduced their activity. I think that sort of club just went out of style. Also, some of them were really bad at recruiting new members -- the older members seemed to be territorial.
That kind of club had a lot more going on than just one main activity. The large ones had things like swimming pools, gyms, and large dining rooms. I guess it was a kind of country club for not-so-rich city folks.
