The art of line-dancing was perfected long ago by idle ranch hands looking to entertain themselves while queuing up to milk the cow or set the snooze alarm on the rooster. Practice this pastoral pastime with today's Groupon: for $15, you get seven weeks of square-dancing and line-dancing lessons from Grand Squares, which holds classes at the First Evangelical Church (a $30 value). Courses begin with a beginners' orientation on August 30 at 7 p.m. followed by six weeks of lessons every Tuesday from 7 p.m. to 9 p.m., beginning on September 6.

Grand Square's professional instructor fosters a friendly atmosphere of old-school fun with engaging interactive lessons. Led by caller and instructor Justin Russell, the fun-fueled classes artfully guide novices through the steps, calls, and complex geometric patterns of traditional Tennessee line and square dances. Toe-tappers are free to arrive with another Groupon-toting dancing buddy, or partner up with one of their classmates, forging friendships alongside impressive rug-cutting skills. Like playing full-contact tiddlywinks or frantically signing the Pledge of Allegiance in semaphore, line- and square-dancing burns calories and bolsters heart rates, all while promising a wholesome good time.
