I travel a lot for my job, and on Friday was coming back to Arizona from a week spent in Washington DC. Trip was via a two-hop flight on United, with a short stopover in Houston. The first leg (a three-hour flight from DC to Houston) got diverted, and actually took 12 hours due to really bad weather in Texas. After finally arriving in Houston, I then ended up spending roughly 30 hours at that airport due to continuing bad weather. Further, the airport was seriously overcrowded, and food supplies were running low, people couldn't get on their flights home, and tempers ran short. In under six hours upon landing, I saw people starting to lose control of their emotions, panic buying $5 bottled water and $6 bags of nuts (vendors purposely raising prices due to the "crisis"), travelers shoving other people in lines, etc. Saw a couple of minor fights break out, too. Basically, what I'm saying is that it's crazy how fragile society is, and how quickly the sh!t hits the fan when otherwise polite and well-behaved people suddenly are denied conveniences, food, water, etc that they expect to magically appear. I like to read apocalyptic genre fiction for pleasure but have always kind of rolled my eyes in minor disbelief when the authors write about cities collapsing in riots and panic within just a few days of something bad happening. Guess what? I was dead wrong and the authors of those books are right. It is very scary how quickly things devolve during even minor "emergency" situations like an airport shutdown due to weather.
