I had an unusual experience in the summer of 2013. I drove up to Lac-Mégantic, to the site of the inferno that destroyed half of the town. Canadians will remember that a train carrying crude oil had jumped the tracks and burst into flames.
When I got there, the press had already arrived and cameras were set up against the police cordon on the main street. All of us were made to stand quite a distance away from the site of the crash. It was believed that pools of un-ignited fuel were still hidden in the wreckage.
