(a) No, I don't smoke.

(b) To the 2 above posts, earlier this year (about a week or so after the JJ's Restaurant explosion in KC) we were drilling and had to cross a 2" gas service to a business. It just so happened that the same day one of those guys with the funky backpack started wandering through our jobsite to check for gas leaks. It was kind of weird timing that he just happened to be there the same day we were crossing a 2" service. He stopped and got real curious and stared at our pothole pit for like 10 minutes, all the while testing for leaks. There were none, and we crossed the service at 52", we potholed it at 44". Watched it go right on by, too.
