Houston has had two major fires from refineries in the last month. A major employer in the area (as well as south Louisiana), nothing comes for free. It's one of the facts of life, you refine chemicals, accidents will occur.
Uncle Lucius has a sobering song of the life of refinery families, and what they do through. Great tune, but listen to the words. Every career path has its risk, and we own a major debt to the men and women who make those facilites function.
Have a great weekend!
