In the Victorian era, extreme sports were limited to teatime without doilies, writing witty satires about earnestness, and riding a penny-farthing down a mild incline. Today's Groupon to Adventures Unlimited in Ocoee would shock such staid sensibilities. Choose between the following options:

• For $42, you get a two-night weekend whitewater-rafting trip for two in October (up to an $84 value).
• For $56, you get a two-night weekend whitewater-rafting trip for two in September (up to a $112 value).
  
  

Each whitewater-rafting trip includes:

• Two-night stay on the on-site campground (a $6 value/person each night; a $24 total value)
• One classic Ocoee whitewater-rafting trip (up to a $44 value/person in September; up to a $30 value/person in October)
  
  

Adventures Unlimited guides rafters of all experience levels through the churning waters of the Ocoee River. The classic Ocoee whitewater-rafting trip sends aquanauts plunging through 5 miles of class III and IV rapids on 14-foot self-bailing rafts. Hydro-explorers spend two hours paddling past rocks, sliding down falls, and playing patty-cake with fish. All rafts are guided by CPR- and first-aid-certified guides who will prepare rafters before trips, decking them out with helmets, PFDs, paddles, and the know-how required to safely scuttle down frothing waterways. When rafters return to base camp, they can relax at their secluded campsite within the park's 31-acre campus, snapping their own photos of Bigfoot or the even more elusive Big Bird. Rafters are not required to stay at a campsite to enjoy the white-water rafting trip.
