Don't know whose line it is, but about 15 years ago a 36" gas main blew out about three miles from my house. Luckily, (and incredibly) there was no fiery explosion, just the force of the psi blowing out of the pipe. Even so, we could hear the roar easily
inside our house 3 mi. away. We had to shout to hear each other outside. It left a hole with a surface area of about a half acre.
(P.S. Can a
hole have "surface" area?)
