I only once caught a water pipe with a spade bit and got a faceful of water. I also only once cut into a power cable with a drill bit. Both times it was for the same owner but in 2 different houses about 3 years apart. What are the odds.
I guarantee I'll tell you the truth and I guarantee I'll tell you what you need to know but I can't guarantee that I'll be telling you anything you want to hear.
