I'm playing the dumb card here. My father in law is concerned that I have to much firewood. I have most of it up on pallets and stacked. Worked all winter on it. I would guess I have close to 10 cord cut. I realize this is not alot, but he asked the question and I did not even have a guess. How long before hardwood starts rot on pallets? Right now it is uncovered, but will be covered for the winter months.
