What about this - I was thinking about the mandatory evacuation out of Florida in which was ordered to avoid the hurricane, and I thought what if FEMA set it up for the evacuees to have a way to get gas and hotel rooms along the evacuation routes on FEMA's dime ?? Wouldn't this allow for those who might not be so willing to flee for economic reasons, to then flee like everyone else can or would ? Otherwise you have people who are living paycheck to paycheck that might figure that they are stuck, so they just stay behind thinking I will just have to ride it out no matter what happens. It could be that if you have a Florida license plate or tag, and a Florida drivers licence to present while on the evacuation route, and you present that at the supported stations or hotels in the safe zone or along the route, then FEMA would automatically kick in to take care of you and your families accomodations until allowed to return Home. This would level the class situation in which money separates the saved from those left behind because they couldn't get out because of a lack of money. If done in a manageable way, and proper ID along with address and registration to match liscense tag were presented, then you would be excepted to get assistance while in route, and until allowed to return home. The wealthy wouldn't need the assistance, but the unfortunate working class poor who would want to leave also, could definitely get the help if need it on or along the way. Just a thought.
Busses could do well as part of an overall plan.
Ran across an article by a military officer who took part in the Katrina rescue who wrote a web page touting up the idea of trains like the military used to have, hospital cars, supply cars sleeping cars, kitchen cars, etc., that could be rolled in and set up. Made sense to me; temporary rails are relatively easy to repair and lay quickly, relative to repairing interstate highways and the like, with the specialized modern track laying and construction trains, and can carry a lot more than caravans of tractor trailers back and forth as well. I'll try and find the link, it was a while ago, and I don't even remember if I saved it.
