I bet at home my wife has some pictures of me digging that thing. I'll ask her tonight if she knows where they are...
Here are a couple to show where we started from
This was last year when i was building a small chicken tractor to get the land worked a little before we planted. We have 3 acres and it's all pretty much like this...flat, dry, and sandy.
My son and I (with his play plastic saw) getting the fallen branches chopped up and ready for the beds. We raked all the leaves and threw them in there too.
