There is already an effective evacuation plan. It's called 'advanced warning'. No one was caught off guard. Everyone knew it was coming and many made the wrong choice of not evacuating. The old 'it won't happen to me' syndrome.
Watch the evacuation with the next hurricane...
Very little warning this time Frank. This went from a measly tropical storm to a ferocious monster all teeth and claws in the relative blink of an eye.
In a perverse way, the massive coverage of all the Flodia hurricans last year may well have encouraged everyoen to stay put now..Loss of life was minimal..hell, more people get killed on the highways in a weekend..so many probably figured..stay and ride it out...protect my property..and get an early start ont he clean-up..they saw all the commericals about the insurance companies coming in the next day and wrting checks on the spot..
All you needed was a car. Absent that, it was stay, or walk out on foot, or hijack a car.
