You assume "cost" means MONEY for the CITIES.
I'm talking about personal COSTS for the victims - in terms of people who are ALREADY sick & injured and will get worse on long ordeals, people who are already exhausted and don't need to try to prop up on a long ride until they finally get there, etc. The longer they have to go, the harder it is for them to hold up, or even take some things w/them.
Never mind the COSTS to those victims trying to get BACK to where they were - in many cases, that too will be their money & credit, anyway (yes, you do have to make people start being responsible for themselves at SOME point). Not to mention the hardships of just trying to handle business/housing arrangements from further away, or making the trip back thru thousands of miles.
