I've had exceptional luck by putting the word out that I wanted cooking wood. I now have a guy at the power company that drops stuff off once on a while and several requests to cut down apple trees. After having the Lang for less than a year I've probably dropped 10 apple trees and should be good for a while. Also some tree trimmers stockpile the good stuff to sell.
