This is Carl , his wife was one of students back around 1998. They invited us to help make maple syrup in their back yard. They tapped their own trees and cooked the sap on this home made “cooker”. The neighbor boy cooked some weiners in the syrup as the sap boiled off….tasted delicious!! After it boiled down to maple syrup we poured it from the large black tray through cheese cloth into containers. They were so kind, they gave us some to take home. What an experience!!
