Numerous ecological regulations impact our fish, yet few volunteers are interested in doing the hard work of registering them to vote. Canvas your local waterways with today's Groupon, offering a half-day rental from Cave Country Canoes in Milltown. This Groupon is good for the following options:

• $10 for a half-day canoe rental ($23 value)
• $14 for a half-day kayak rental ($29 value)

Inside the water vessel of choice, you'll paddle down the beautiful, clean Blue River and take in an eyeful of wooded hills, limestone bluffs, and friendly forest critters for approximately two to four hours of natural wonderment. The river is a Class 1 stream, so it provides wetventures for beginners, families, and groups. Cave County Canoes is equipped and experienced in providing unparalleled water excursions. Channel your inner water-Lance Armstrong as you fearlessly paddle past a bevy of possible animals including otters, blue herons, and hellbenders, the continent's largest salamander, in your boat built for one or two.

A half-day trip with Cave Country Canoes also includes complimentary bus transportation from the operating base to the put-in and/or take-out location, safety-video screening, life jacket, litter bag, and a map. The raftery is open seven days a week through August and requires reservations. You can schedule your trip any available time after 8 a.m. Availability decreases after Labor Day, with weekend trips only for the duration of the season (until mid-October).

Note: One Groupon is good for one seat in the canoe or kayak; additional riders must either pay full price or also have Groupon to receive discount.
