Exploring new worlds—be they unchartered stretches of ocean, labyrinthine build-it-yourself furniture warehouses, or neighbors' padlocked basements—can be a broadening experience. Equip yourself for oceanic horizon-expansion with today's Groupon: for $20, you get a Discover Scuba class at Landshark Scuba and Snorkel Center (a $40.35 value).
Landshark Scuba is one of South Dakota's only Professional Association of Diving Instructors–certified centers; the facility has been educating landlocked locals in the diving arts since 2005. With the Discover Scuba class ($35), novice divers will be introduced to scuba diving within the safe and relatively shark-free confines of Landshark's pool (a $5.35 pool fee is included with this deal). Diving basics will be covered by Landshark's staff of friendly and experienced masters of maritime mobility. Should you choose to pursue further diving instruction at Landshark, credit from this beginner's class will count towards your PADI Open Water certification.
Landshark will provide all the necessary diving equipment for your aquatic immersion; simply arrive in appropriate swimwear, bring a towel, and brace yourself for the watery wandering generally provided only by flipper fins and a third lung. Basic scuba-diving training may later prove to come in handy on vacations, deep-sea treasure hunts, or acts of revenge against kelps, so be sure to call ahead and reserve a spot.
