I agree. Many people seem to be assuming that they will be the only people in them thar hills. No one has mentioned what is likely to happen when half the people from any city ALL head for the same hills! Off the top of my head, here are a few problems you might be likely to encounter:

* Edible wildlife would take off or be killed.
* Many people would bring their pets, which would disappear just before dinner.
* Edible plants would disappear.
* Water supplies contaminated.
* Sewage like you've never seen before will be lying on top of the ground and within easy reach of the waterways. (Even month-old kittens are housetrained better than most humans.)
* People who brought stuff will be attacked by those who didn't, or who ran short.
* Those who have weapons will be using them.
* Dead bodies will be lying all over the place.
* If anyone has an infectious or communicable disease, it will spread.

Home looks better by the minute.
