America has always been the most extreme country, from the Boston Tea Punchings to having the first man swear on the moon. We hold this shredding guitar solo to be self-evident with today’s Groupon: for $147, you get a spring high-water rafting trip from Wilderness Tours (a $294 value). The Memorial Day weekend trip departs from Foresters Falls on Friday, May 25, and concludes on Monday, May 28. The trip includes:

• Two full days of rafting with use of wetsuit
• Three nights of camping (tent and supplies not included)
• Seven meals
• Use of facilities
• Evening entertainment<p>

Seasoned guides draw on more than 30 years of paddling to help rafters of all experience levels tame the roiling Ottawa River. Water levels reach their apex by Memorial Day, forcing weekend rafters to navigate gigantic rapids generated by spring rain, melting snow, and the tears of black bears stung by waking honeybees. Participants arrive on Friday evening and trips commence early Saturday with a safety briefing and paddling practice on the river, during which rafters learn the teamwork they will need to do battle with such whitewater behemoths as Bus Eater and Gladiator. Periodic stops punctuate the day’s float, as guides travel ahead to scout upcoming rapids and rafters warm their bones with hot soup and barbecue fare. Sunday’s paddle-a-thon traverses the tight and technical Middle Channel and concludes downstream with refreshing beverages, high-fives, and a ceremonial raft burning to please the local river gods.

Waterlogged groups make their triumphant return to the adventure resort, where they can soak in the hot tub, view a video presentation of the trip, and reacquaint themselves with terra firma by dancing to live music. Optional trip upgrades include bungee jumping ($79) and overnight stays in the four-person Cedar Cabin ($97/night).
