I don't care where you used to work.. I'm just telling ya these are major ACTIVE lines. You know, the kinds with up to date warning signs sayin there's a gas line there and on both sides at that which to me says they're connected. They run east to west, or vice versa of each other. I even thought maybe a small earthquake, n the OP's theory could be correct, BUT there is a mafor pipeline that IS most definitly there. I'm tellin ya, I've been driving every back road around here trying to get home from Charleston because the entire damn interstate is closed coming onto 77 N outta Charleston. I was at work, but my niece and sister n law was at my house with my young boy and they said the house shook, n they had thought a plane had crashed. My niece thought the house on top of the hill was on fire cause the interstate is right behind it where it happened. They thought it sounded like a jet engine that kept on roaring. Many local including my parents thought a big plane crashed.. I know the roaring sound is consistent with the gas line that blew up back in 02. I was about 500 yards away and it was probably 400 foot high easy, but that location is a good 15 20 miles southwest from where this happened.
