Between yesterday and today I have dug a 3 foot deep, two feet wide, 30 foot long trench in our yard trying to find one of the valves for the sprinkler system. The soil of 2-4 inches of barkdust with the rest being clay full of rocks and tree roots. I finally found it. I'm beat, tired, dirty, and headed for the shower. Where is a back massage when I need one?
