Wood racks protect your wood from miosture. This prevents mold growth. Also the cord of wood racks allow the firewood to fully cure. With fully curred wood your fire burns more clean and hot.
Keeping your cord of wood on wood racks allows the air to circulate through and around cord of wood. With a good wood rack your cord of wood will be up off the ground. This prevents crawling insects off your wood. No bugs means no other animals will be hunting near your cord of wood racks. (mice, skunks..etc)
