Now that I'm living in a town with two bars and one church, about 10 miles from the nearest "shopping center," the concept of a city or three catching a case of summer flu doesn't bother me all that much... My neighbors are mostly armed, and, well, when you have to get help to move the ammo...
If things start to get funky, I'm gonna pull the kids outta school, and hunker down. We've got food for probably at least a month or two, and if I can kill off some of the coyotes, some of the small game may come back...
I mean, I'll feel sorry for folks and all that, but when you cram 10,000,000 or more folks into a tiny area, you get problems.
