I've always felt that one reason I've continued to go to the country western place here in Portland (actually Tualatin) is that there isn't just one dance to do. CW dance places have several to many different dances. West Coast Swing is a big staple here, very often when there is a line dance, or whatever, going on at the same time.
CW has "always" had more than one kind of dance. See Lloyd Shaw's books: "Cowboy Dances" and "The Round Dance Book" published in 1939 and 1948 respectively.
Then there was what one East Coast dj dubbed California Mix, which they actually have played in the LA area (but without calling it that). (To me the Western Swing/ WCS / Country connection has been there since WS/WCS started. But there is no smoking gun." Now a days, people just don't think of "country" and Los Angeles becuase they don't know the history.) Something for eveyone, sort of. Or at least enough other stuff that you aren't doing the same dance, or listening to the same beat all night.
Some communities venture into other dance forms when they get bored with doing the same thing all the time. Lindy Hoppers and "Blues Dancing". Westies and "Swango" are two examples that come to mind.
Both music and dance were a lot less seperated by genre back in the day, but it's a good model for cotinued interest. At least it works for me and the folks who have been going to places like Cowboy Country in Long Beach, and Jubitz and Bushwhackers here in the Portland area for years.
