In the about 1979 I took a course in Country/Western Dance.  This was the Tucson style (not many line dances--more "free-wheeling," something you could even do at a disco, with lot of twirls and spins).  Later, the instructor (Pam) and I began teaching it together--we were spending lots of time together, anyway!  This form of dance was very big in the Rocky Mountain West, peaking around the "Urban Cowboy" time in the early-to-mid 1980's.  In Boulder at the time there were at least three good places to go--"Peggy's Hi-Lo,"  "The Olympic," and "Arapahoe Ranch" in particular were hoppin.'  In fact, this was a great musical era in Boulder, with 12-15 live bands--with music of all types--on weekends and nearly that many during the week.
    It's still great fun (something about dancin' of any kind that stirs primitive happy juices!) and good exercise.  I still go, occasionally, down to the Grizzley Rose, but miss the big Western Swing era in Boulder.
