What do you mean, "not that big a deal to run a power line underground"? I need some lights by the front walk, does anybody want to come over with a shovel and help dig a trench for the conduit? ... ... ... Right. I thought not. So they're going to be solar powered. A city has better digging equipment, but also pays more than I do in employment costs, so I bet it comes out about the same.
