Seeding the Backyard, part deux

I spent a couple of hours today going through the soil(hand 'tilling' it) and pulling up rocks and weeds. I put the rocks into a used 5 gallon paint bucket and, when its full, I dump the bucket into the dumpster in front of the house that's being built next door. There are a lot of rocks. And weeds. Some of the rocks are rather sizable.
