Ep. 17 - Nature's Junk Food - Sap!

During this episode, Bill and Steve talk about nature's junk food - sap! Join the guys as they cover how sap moves through Maple trees, as well as how climate change will affect Maples and the sap collecting season. They also interview two volunteers at the Beaver Meadow Audubon Center about turning Maple sap into syrup, cream, and sugar. Enjoy the episode!
