Keith and Audrey Aanenson, Luverne, have been dancing with the Hollyhoppers for nearly 40 years.
That makes sense, since the national square dance theme is "Square dancing is friendship set to music."
Aanenson said he also likes to dance for the physical exercise. "It's the same as jogging four miles," he said of a typical club meeting. "You're wore out in the end."
More than 100 past and present Hollyhoppers showed up Saturday night at Brown Elementary School gym, Pipestone, to dance.
Frequent Hollyhopper caller Don Nugent, Trent, S.D., called the anniversary dance.
When asked why he enjoyed the pastime, he said, "You can leave your troubles at home and dance your cares away," he said.
He said square dancers always have a good time, despite the absence of alcohol. "Liquor is a big no-no," he said. "You can't square dance if you've been drinking. You can't keep up and it breaks down the square, and that's not fair to the other seven dancers."
