This one’s a quote from a caller’s husband. Dottie Welch is a Canadian caller (no website that I can find) from Nova Scotia. Her husband, Gary, is an astronomer. Here’s what Gary has to say about square dancing:

Although not a competitive activity in the usual sense, square dancing is definitely a “team sport” in which 8 people work together to execute intricate geometrical sequences in time to music. The building blocks (individual “moves”) are learned, but dancers do not know how the caller will put them together until it happens. Successful completion of a difficult sequence demands total concentration, and leaves a wonderful sense of accomplishment. Dancing to a talented caller who combines demanding choreography with good music is an exhilarating experience.
