Back in my pipe laying days we had fortis come out with their nat gas line locator bullshit. They marked it out where it wasn't. It was actually on the other side of the road. Not much faith in that.
Interesting. A friend of a friend wanted to dig in his backyard in the early 2000s. Calls ALL the utilities. His front yard looks like an urban art project w/all the paint marking the hot zones. Backyard is declared utility free, dig all you want. He knocks down a portion of his fence, rolls the rental JCB ho' into the back yard [HTML_REMOVED] digs….. 2 feet down hits the natural gas line….. [HTML_REMOVED] much hilarity ensues! 911 call, city shows up, gas guys show up [HTML_REMOVED] much finger pointing w/the general mood looking to throw the homeowner under the bus. Homeowner points out the art project on his front lawn [HTML_REMOVED] the multiple calls [HTML_REMOVED] on site visits giving him the go ahead. Dance monkeys, dance! Gas co. finally relents [HTML_REMOVED] picks up the 10 grand bill for emergency weekend repairs. Turns out the house, which sits on a corner gets its gas fed from the main street thru the backyard, Awesome! Or put another way, what Mr West said.
