When I was a kid, we tapped a bunch of trees in the Nicolet Natl forest in nordern Wisconsin. We found an old bathtub at the dump, cleaned it out, and propped it up over a wood fire outside my friend's cabin. We musta got about 30 gallons of sap and simmered it for days over that fire. It yielded about 2 gallons of the sweetest, sugary-est maple syrup you could ever hope to rot your teeth.
....I doubt that I'll be going thru that again, thank you
