The Engineering, Design, and Innovation Fellow 2020 cohort stayed at Kiptopeke State Park (VA) to design and construct a concrete boat to hold two of them at a time.  On the second day, they kayaked around the historic WWII concrete ships sunk at Kiptopeke State Park.  The State Park Interpreter led the kayak tour and explained the history, mentioning that the ships were active in the Pacific Theater and after the war, were sunk at Kiptopeke to serve as wave breakers.  They then designed and constructed the frame for their concrete boat.  Here is a photo collage of Day 2.
