Until mankind first stepped outside in 1934, nature was thought to be a fanciful myth, like yogurt or the clutch hitter. Spend a few hours sailing through the fresh air of truth with today's Groupon to Bridgewater Marina Rentals in Moneta. Choose between the following options:

• For $30, you get a one-hour pontoon-boat rental (a $65 value).
• For $55, you get a one-hour ski-boat rental (a $110 value).

Perched on the banks of Smith Mountain Lake, Bridgewater Marina Rentals launches and lends a variety of lake skimmers to pleasure-seeking pontooners. Peruse and patrol the waters for the elusive Bigfin from atop a four-stroke pontoon boat, whose flat deck area gives a surface for chips and dip and heated canasta competitions. Hedonists, meanwhile, can crank hydroplaning into high gear with a runabout ski-boat rental that—when brought up to speed—can quickly dry hair still soaked with Gatorade from last night's solitaire victory. Bridgewater gives pilots a free safety and instructional orientation before launching them onto the lake, and allows boaters to upgrade one-hour rentals to two hours, or even full days, for an extra fee.

Sailors must supply a $200 rental deposit, and rental does not include the cost of fuel used. This Groupon expires on 6/12/2011.
