With our country's once widespread network of interconnecting moats largely replaced by interstate systems and zip lines, traveling by water is often overlooked. Rediscover America's aqua-portation roots with today's Groupon: for $25, you get a two-hour standup-paddleboard lesson at Kayak Amelia, located in Talbot Islands State Park (a $50 value).

The highly trained water wizards at Kayak Amelia instruct landwalkers in the art of standup paddleboarding with two-hour lessons held on serene waterscapes. After equipping students with paddles, mermaid repellant, and extra-long, 12-foot boards designed for easy balancing and navigation, aqua gurus orient and instruct participants on land before pushing off into the calm waters of the Huguenot Park Lagoon. Once pupils acquire fashionable sea legs, they'll tour the surrounding waters, learning of the local ecology from their guides and stopping along the way to sidle up to sandbars and beaches. Instructors help refuel tired bodies by handing out complimentary Kayak Amelia cookies, great for biceps that run on baked goods. No experience is required, and paddleboarding is suitable for all adventurers ages 12 and up.
