This has been my worst year for cutting cables and wires running under ground. I believe it's been 3 cable tv lines and a half dozen underground dog fence wires up until today. This is not to big a deal.. as I can fix them. Well today I believe I hit a telphone line It appears that I only opened up the outer jacket. The inner wires looked to be intact... Not sure though. This cable was barely an inch underground. I'm not sure what the code is.. 4-6" or 6-8" but I know it's NOT AN INCH! WTF? Anyway.. has anyone done something like this? Do you think I'm liable???
