From the archive: 4/25/2003 - Maple sap pipeline in Northern Maine (or Canada?). There are like miles of this stuff going out into the woods. Apparently they tap the trees and then feed small tubes from the tree into trunk lines, which tie into this pipe. The building in the distance is the maple shack where all the sap ends up for processing. I saw this on a men's retreat that was organized by the Calvary Baptist Church in Warren Maine.
