Before the invention of the boat, the most efficient way to make it from one shore to another was to bribe Bigfoot to throw you over. Navigate the waters sans Sasquatch with today's Groupon: for $9, you get one adult ticket to a Patoka Lake boat tour from Patoka Lake Marina & Lodging in Birdseye (an $18 value).

Patoka Lake Marina & Lodging's guides enable clients to explore the second largest lake in Indiana and its animal inhabitants during boat tours on Wednesdays from 2 p.m. to 4 p.m. Located near Hoosier National Park, the area teems with wildlife, including ospreys, loons, herons, and the elusive bald eagle. Climb aboard the marina's new 60-foot Patoka Voyager for a two-hour tour of the picturesque lake, and relax as a guide takes you along the scenic shoreline, detailing Patoka Lake's history and singing children’s lullabies. There's a cash bar available as well as indoor and outdoor seating. Children five and under can partake of the scenic water fun for free when accompanying a ticketed adult.
