Seriously starting to think I'm not going to bother covering the wood piles anymore. Last year I had them covered with tarps. Everytime it got a bit windy, tarps were all over the place. I had them nailed down, wood over the top along with tires, other lumber, pieces of metal, etc. This year I thought I got smart. I got a bunch of OSB and plywood and put that over the top. Screwed the pieces together and weighted it down with pieces of wood. Figured it would be plenty heavy. Yeah right. First small wind storm we got.. I'm talking only 35-40mph winds, they all flew off! I started fixing it yesterday. Got one stack back covered and used over 100ft of rope to tie it down. I didn't have time to finish the last ~10ft before leaving for work. Got out this morning to finish tieing it down and that part is ripped off and way out in the woods. I got all my stacks tied down today, took almost $40 of rope and eye bolts though... and I'm not sure that will be enough even when we get real wind storms. Happened every winter and not uncommon to have 70-80mph gusts.
