The utility companies do, phone and cable don't on their laterals. But then
we always have the DIYer that gets tired of digging and burys romex, or if
he is real cheap, that lamp cord, out to his new Home Depot light post. Or
maybe he needed to add that extra circuit for his Christmas lights out in
the middle of his yard. He hardly got more than 12-16" down. Never consider
the obvious do ya! You just never know what the last guy did. I loved the
DIYer that had a speed bump in his drive way. The PVC went right across with
asphalt over the top. Of course he was proud that he got it over there with
such ingenuity.
