Time to register for the Rock the Boat Cardboard Boat Races is running out. The event organized by Whirlpool employees is set for August 27 at The Inn at Harbor Shores, and the registration deadline is next Monday. The Cardboard Boat Race will raise money for the United Way of Southwest Michigan. Everyone who takes part will get to make a small board out of cardboard and then see how long, or if, it floats. You can also sponsor a boat if you’d like to contribute. To find out more about signing up, go to UWSM.org/RockTheBoat .
