I am a longtime subscriber to MOTHER EARTH NEWS. I always look forward to each new issue and devour it cover to cover. In western Washington state, it often is too wet for wood to season in the open air, so here's my tip:
To build a cordwood rack, I used two pallets, some 2-by-4s, some scrap lumber and three ½ -inch by 10-foot plastic pipes to build a drying rack. After filling the rack, I attached the plastic pipes and covered the rack loosely with a tarp to allow next year's firewood to dry.
