Fulfilling Murphy's Law, the buried lines always run right where I want to plant something. I've nicked the phone line several times, with no ill effects--if I sever it, I think I'll just get internet phone service and not mention it to Bellsouth...and be really careful about not hitting the cable TV line (also buried) which brings internet service into LMAID World Headquarters. I'm more worried about cutting the big phone line that serves the entire street, including one neighbor who works for the phone company. Let's don't even talk about the buried power line. I give that one a WIDE berth when I'm digging.
When we first bought the house, I had enough sense to summon the utility locating service to mark the lines. They came out and marked all the lines with different colored paint. I took photos so that I would have something to refer to later, but they said that the actual line could be located like 1-2 feet on either side of the painted stripe. Thanks, guys. That helps a lot.
I was talking with a geologist friend of mine one day about the problems of gardening around buried lines, especially when the photos aren't clear and you can't remember how close the phone line is to the tea olive.
"I wish I had one of those locator machines," I said.
"Go get me a couple of those survey flags," she said. "I'll show you a trick."
I retrieved two of the little red flags that I had used for a previous project and handed them to her. She bent the wire stakes into an L-shape.
"Here," she said. Hold these out in front of you, parallel to each other, and walk. When you get
I looked skeptical.
"No, really. It works."
Wary of the power of suggestion, I handed the flags back to her. "You do it," I said. "I already know where the lines are, and I might unconsciously move them over the right location."
So she took the flags and began walking across the yard. To my astonishment, she located all four of the buried lines.
I'd be interested to know if anyone else has tried this, and with what success. Any of you science types know how this works?
