While I don't discount that a building on a hill has its uses, I do think that such a structure would require more extensive drilling and the like for water collection (depending on the environment) and other resources.
"Close to civilization" is a highly relative term. My parents believe that they live close to civilization because it doesn't take an hour to get somewhere (it only takes half an hour). I consider "close to civilization" to be two blocks from the nearest convenience store. Okay, jokes aside, I would like to nail down something a bit more concrete than "close to civilization." The average person walks at a speed of about four miles an hour. That means that in a ten-hour day, not accounting for breaks, a normal person can walk forty miles or so. I'd say that's a safe distance from any major population center. However, you also have to take into consideration that people will be moving out of the cities and toward the isolated areas when the shit hits the fan. Consequently, would it be better to build a safe house within the city? Just food for thought.
As for being too close to civilization because of the zombies, you should keep in mind that zombies are nomadic. They move consistently, without the need for sleep or personal breaks. They follow the food, so either way you scramble the egg, you're going to have to deal with some number of zombies at some point, and there's no way (that I can think of) that you can accurately calculate where zombies will and will not go.
I think you're on the right track, Gyro, but I do think there are many, many, many variables to be considered. Thanks for the input.
