Joe,
Glad the trees are done, and now you can start the recovery process. You should have rented one of those post hole augers as they do a pretty good job of getting through our hard pan. Just have to use a small one first to get the first hole through and then go to the larger ones.
Tru,
That sounds like a nice seed barn you built. The steel roof would be great here except for the sun and heat. My neighbor had a huge steel garage built and they said they won't use wood supports or anything because the heat can cause them to burn.
