Paine Products from Auburn, Maine apparently use 4,000 to 5,000 pounds of dried balsam tips every week. Local loggers and tree farmers bring in offcut tips from their operations and these are ground down to be put into pillow fillings. The leftover sawdust is used to create the infamous scented sticks that can be burned in the log cabin incense holders (numbers via Mooseville).
These would go perfect w/ those "balsam fir" colored Field Notes you got. You didn't miss those did you?
