Thanks Al!

I had thought of using PVC at 1st but that would require me to dig a "Real" trench. Being I live on 3" of topsoil with rock below I couldn't afford the type of ditch digger to cut a large trench. So using the high pressure nozzle on my power washer, I was able to cut a perfect trench for the gray 12ga romex. The other bonus for this method was there was little disruption and tearing up of the lawn. The only drawback was some shallow spots due to the rock.

Can't wait for summer!
