I have had my eye on a dumpster at work where they throw away all sorts of wood items. In fact it is where I found the wood to build my first two deep bodies and 3 medium supers. The other day I got 110 feet of 1X12 out of that same dumpster. very clean with not a lot of nails or holes in it. I am not sure just what all I will make from this. I want to make a second hive, at least a couple of nuc boxes and a couple of yankee nuc boxes to sell bees with in the future. At any rate thought I would share that if you can find a likely location it is worth keeping an eye on. IT took over 6 months total but I have found enough wood from one dumpster to make over a dozen hives now.
