Bottom line, our roads and infrastructure is not set up to handle a mass evacuation from such a large city. Infrastructure is set up for average needs. This should be a reminder to all to think about. Especially if "other" things prompt an evacuation, like a missle strike from N. Korea.

Yep. This is a 500 year event. A plan for this? What would the cost for this ‘what if’ scenario have been? Who would have voted to spend that much?
