Thats what I'm afraid of, I have about 12 cord outside on the concrete in my barn lot. So every week or so I get the skid loader and stir the pile. The top of the pile usaully is really dry but the center is soaking wet so I try to make sure it gets rotated to keep from rotting until I can split and stack it.
With the concrete bottom, if you get it on skids, stacked, it'll be easy to move with forks(if you stack for stability), there will be airflow from the bottom, and the bugs will leave it be. Covering the top of skid piles will be worth the effort, but if you can set up a shed roof, just posts and metal roof, with three sides open to air, you'll not have to worry about that wood for many years to come. The worst that will happen is an occasional mouse nest or over-wintering insect.
By the way, its also what I do, and once I stack it in there, it could stay indefinately.
Once you figure out the solution that works for you, post a pic or two, we like pics of wood.
