David helped me on a Saturday find our power and phone lines underground. They tried to do the work on Friday, the day I called. However, one of their workers got delayed. David said he would come out on Saturday and do the locating for me. He found the lines, marked them, and the depth of the wires. He also marked our propane line. The work was quick and done as expected. If I wouldn’t have asked so many technical questions, because I was fascinated with the technology, David would have been done much quicker.
