Summer Solstice, Riverfest, and Cardboard Boat Race Challenge!

Summer Solstice 2019

Sunday, June 23

The Old Manse, 269 Monument Street, Concord, MA

You're invited to a fun-filled and magical celebration of Summer, presented by The Umbrella Arts & Environment Program, The Trustees, SuAsCo River Stewardship Council and OARS




Can you make a boat out of cardboard and paddle it 25 yards?  Before it sinks? 

Can you design your boat not only for maximum flotation and speed but also to blend in with the river habitat? In an hour and a half?

We challenge you to test your engineering skills and have a blast building a cardboard boat to race in the Concord River! You just bring your team and intrepid spirit, and we’ll provide the materials!

Winner categories include: First boat across the finish line; Most creative Concord River habitat design; Most spectacular sinking.
