Bodies of water are frequent metaphors in poetry due to their unfathomable depths, unknowable sprawl, and unattainable porpoises. Set sail into the enigma with today's Groupon to Paradise Rental Boats in Bloomington. Choose from three options:

• For $100, you get $200 toward a boat rental, valid Monday–Friday.
• For $110.00, you get a four-hour rental of a two-passenger waverunner (a $249 value), valid Monday–Thursday.
• For $119, you get a four-hour rental of an 18-foot runabout, plus a choice of either a wakeboard rental or a tube rental (a $274 total value), valid Monday–Thursday.

All options can be redeemed on weekends starting 9/23/11.

The clean, seaworthy vessels docked at Paradise Rental Boats allow visiting aquanauts to circumnavigate Lake Monroe. The 18-foot runabout comfortably seats 6–7 passengers and propels wakeboard- or inner-tube-borne followers to new heights of glory. Adrenaline-pumping two-person excursions on the Yamaha WaveRunner allow lakefarers to jet in circles around slower boats and race the arrogant trout loudly revving their fins underwater. Those who opt for a rental credit may use it on a 21-foot party barge ($199 for 4 hours), which accommodates 11–12 passengers on its comfortable lounges and rear sun deck, and features a Bimini top and the option to tow an inner tube behind it.

Paradise Rental Boats does not take a security deposit but they do need an imprint of a credit card in the renter's name. Guests are also responsible for the cost of gas consumption, which is generally 5 gallons per hour of engine time but varies depending on how much gasoline guests drink. Before their voyage, renters are encouraged to read Paradise Rental's FAQs.
