And so, Sam, Chuy, and I drove toward the coast, out Main Street and on to 90A, where there was, indeed, no traffic. At all. Somewhat further on we sped past a beat-up scarlet Nissan with the words "Rita, go away bitch" spray-painted on the back window. Fifteen minutes later, we hit gridlock.
She had a pretty good plan, use minor highways and roads to get through as much of the city as she could.
She tells a story of how she used a GPS device to reroute away from the Interstate and how she ended up taking her son and dog through small towns she had not been to in a long time.
If you are looking to evacuate your city you need to have your escape route not be the Interstate, almost no one plans for these things, they just take the first route that comes to mind: The Interstate. It is also a habit, they use it everyday to get to work.
You are planning ahead you take a different road to work to see how it is during rush hour (as close to an evacuation as you can get) and often it is rather quiet.
I have a routed planned to my wife's parents house using nothing but state highways. and good maps that will let us use even smaller roads.
Which road would you take?
