Walking backward while talking is useful for leading a tour, demonstrating a moonwalk, or retreating from a room full of ominously staring toddlers. See the reverse saunter put to good use with today's Groupon: for $25, you get a tour for two adults from Princeton Tour Company (up to a $50 value).

Mimi Omiecinski created Princeton Tour Company to share the rich history of her favorite town on walking tours, ghost tours, and pub and grub crawls. Armed with facts exhaustively vetted by the Princeton Public Library, she and her fellow walking encyclopedias bestow knowledge to groups of 4–15 on up to two-hour jaunts through approximately 3 miles of terrain. The most general University Campus & Genius Neighborhood tour teaches tour-goers about both the town and school while passing through such renowned stretches as Writers Block and Presidents Row. Follow along on the Literary Greats Walking Tour, where you'll visit the haunts of some of the world's greatest wordsmiths, including T.S. Eliot, Toni Morrison, and Jamie Farr, or explore the changes in American construction style from 1690 to the 1960s on the Architectural Walking Tour. The pub crawl combines beverage drinking with knowledge learning, making stops at historical and architectural sites and watering holes.
