I don't think this example has to do with anything to do with fans in the stands being a good or bad thing. This was one of those things that I for one worried about going into this hurricane season-I read (correct me if I'm wrong anybody who lives in Lake Charles or has family down there) that something like 90% of Calcasieu and Cameron parishes don't have power two weeks after the storm still-which means Lake Charles isn't livable RN basically. You get 200,000+ evacuees (most of which likely headed for Northern Louisiana) this unfortunately isn't a surprise.
I am sure it will be rough for awhile. My parents had no power for a little over three weeks after Michael.
