.....we bought a german shepard. We did not expect that he would obliverate ALL the grass in the backyard, which has a 3'9" drop from east to west. Needless to say, with no grass, we have a raging "river" every time it rains. So, Friday, I had 2 yards of stones delvered and laid it out to, hopefully, remedy the mud hole problem. Gonna install a diy/redneck french drain system to carry the "river" underground.......fingers are crossed.
