Thanks Judy, we're really pleased with how it turned out. I'll see if I have a pic of the whole thing and post it.
I picked up some migrant labor today and got a major portion of the trenching done (certainly the hardest part), before getting rained out. So now I have the electrical wire in from the BBQ all the way across the patio and back along the house towards the garage. From there on it is easier digging and the only obstacle will be the block wall where it attaches to the garage. I'll try to get it under the footing and if that doesn't work I'll use a rotohammer to drill a hole through the concrete and thread the wire through that. The electrical service panel is just a couple of feet on the other side. Once I get it to that point I'll have an electrician hook things up on both ends. Then the fun stuff can start again!
