Still seems like there is some confusion. Of course having wood top covered or in a well ventilated shed won't hurt, but it hardly makes any difference if wood you intend to burn in two years is getting rained on today, either. If the humidity is 100%, the wood can't be drying covered or uncovered. Now if it's wood you intend to burn in a couple days or a week - yes, it makes good sense to cover it - or if ice / snow is going to be an issue - even I cover mine in these situations. But trust me, most every forest floor is littered with crackling dry wood which has never been covered a day in it's life.
