That guy is just down the road from my parent's place. Sad thing is, he was complaining to the gas company about the smell of a leak. Hit the light switch, and BOOM! I've seen enough damage from propane leaks... blew up a school out in South Dakota, the principal and the maintenance guy were checking out the smell, principal hit the switch, maintenance guy hit the deck... principal didn't make it.
Another case, the town of Volga had a close call, one storage tank had a pipeline to Land O Lakes dairy processors, had a propane smell in their loading docks, investigated and found the pipe from the tank had ruptured. Town was evacuated for over a week, had to drive 20 miles out of my way to get to work.. if that one had gone, the town would have been leveled, and Brookings would have suffered from the shock wave..
