Lewis and Clark were both hobbled during their great expedition—Clark from resentment at his second billing and Lewis from a Lego slipped into his hiking boot by Clark. Enjoy noncompetitive nature excursions with today's Groupon: for $13, you get a 30-minute airboat ride from Black Hammock Adventures in Oviedo (up to a $26.70 value). This deal is not valid between December 24, 2011 and January 3, 2012. Black Hammock deploys vessels every 30 minutes from 9:30 a.m. to 5:30 p.m.

Whipping through the wetlands at 45 mph, Black Hammock Adventures has been leading high-speed gator-chasing expeditions for more than 15 years. Each 30-minute ride will glide over the silvery water of Lake Jesup, one of the most alligator-populated waterways in Florida. Crafty travel guides will slalom through narrow creeks and shallow wetlands, seeking out the secret areas where alligators sun themselves and shred their tax returns. After completion of the velocitous venture, animal lovers can slow down on dry land with a stop by Black Hammock's wildlife exhibit or enjoy a lively libation at the Lazy Gator Bar. Passengers are advised to sport earplugs during tours and to abstain from administering root canals upon adolescent alligators without receiving written permission from their parents first. Black Hammock advises passengers to depart in the morning and evening hours during summer months and during the midafternoon during the winter to catch alligators when they’re most active.
