I get my stuff from:
Anderson's Maple Syrup
If you are going to do it in any quantity greater than a few quarts, lines are the best way to go, it saves a ton of time hauling sap around.
Sap storage is a pain, what types of large containers do you have the lines going to? Can those blue plastic barrels be used?
I would like to have the evaporator closer to the trees and eliminate the hauling.
