The pink thing near my foot is a yardstick (3 feet). Gives you an idea of the size of the piece of Rutherford County that I removed. It was between 4 inches and 12 inches deep. Sledgehammer until crack appears in limestone and pry it apart. Not at easy as it sounds, but I did it with the help of Submariner hammering the prybar into the crack. On to more lawnmower blade eaters!
