Getting ready to dig up backyard (6/8/11)

The backyard was full of break-your-ankle-sink-holes and hills.  There used to be a huge tree that came down a few years back which left probably a 5 foot hole that was very sunken in.  Then up by the house there was a pool so it was all weeds, no grass.  It was just a mess.  Mike decided the best option would be to til it all up and start over.....so that's what we are doing!  Here are before pictures:
