I'm glad you are getting a load. I can't get that mountain of blocks out of my head; I'd take a dump truck load of them if I could. Looking forward to pictures of your stacks.
Brad, those look large enough to crib and that is difficult to beat for not only drying the wood but also for making strong wood stacks. Get all you can!
I'm going to pick up a load on Thursday so I will be able to see first hand what size pieces there are. It's supposed to be a mix of ash, maple and oak so I hope this works out to be a good deal.
