I'll be doing that soon. So far, I've just been too lazyGreat Score!
Split it up and stack it loose, so air gets all around it. I was told that Oak will "Air Dry" at a rate of 1/4"-1/2" per year, and I would assume Apple or Sugar Maple would be similar. If you wanted to speed up the process, I bet you could cut up some small chunks, load them on a cookie sheet and into the oven for a few hours. Worth a try....
