It's possible that I'm just taking one wacky idea way too far .... I've made all sorts of structures now on sleds. Basically two 2x6's with some 2x4's on them, then some sort of metal roof on top of that. I make the metal roof extend quite a ways so that I end up not putting a drop of paint on any of the wood. I really like this. I move these structures around on a whim by dragging them with the tractor. I have a sawmill, so the wood is sorta free. And I have a source on metal roofing that makes that free too (although it often isn't pretty). So now I've got a bee in my bonet about honey for next year. I'm cruising through catalogs and gearing up to purchase materials. A lot of these hives come unpainted and I'm thinking ..... Why not put eight hives on a sled with a metal roof? Okay - so this is the point where I ask the experts. There is probably a very good reason to not do it this way. I'm just too much of a newbie to see this reason. Anybody?
