I'm sure some people can't afford to prepare as well as others. Money definitely makes a difference in situations like this.
But there are a lot of people waiting in the various lines with nice clothes and nice cars. Those people don't have much of an excuse. Days before Frances hit, my car already had a full tank of gas. I mean, come on... if you learned nothing else from Charley, you learned this. Fill up your car! Go buy some groceries. Stock the fridge. Get some cash. None of this requires special equipment or spending money you wouldn't have anyway.
