From 6:30 to 8 p.m. Aug. 9, Plainfield Park District will hold its Cardboard Boat Regatta.
Park district residents ages 10 and up with responsible adult are invited to build a boat out of cardboard and duct tape (provided by the park district), then test its buoyancy by piloting it on the waters of the Ottawa Street Pool. Awards categories include fastest boat, most team spirit, and best design.
The cost is $5 per team. Admission is free for spectators. For regatta rules, visit plfdparks.org.
