Numerous ecological regulations impact our fish, yet few volunteers are interested in doing the hard work of registering them to vote. Canvass your local waterways with today's Groupon: for $29, you get a four-hour stand-up paddleboard rental from True Blue Water Sports (a $63.60 value).

True Blue Water Sports fosters nautical excursions with its selection of body-toning standup paddleboards. A cross between a surfboard and a canoe, paddleboards combine a canoe's ease of rowing with the crunchy taste of a surfboard. Grab a rental from the shop, located just blocks from the beach. Flattened boards sail smoothly through small lagoons or over the sparkling crystal blues of a tributary while proffering lofty views of pristine white sands and myriad wildlife. The watercraft strengthens cores and limbs with a full-body workout next to scenic panoramas, or for a more challenging adventure, out on the open water, where waves or harnessed dolphins propel boards back to shore in thrilling bursts of speed.
