You know, even though I still agree the the zombie upsrising is just around the corner and will happen, I'm finding it hard to wonder how it really could spread into a worldwide epidemic. I mean, if it takes a while for the effects of the disease to kick in it could spread nearly worldwide, but there are places on the planet that just wouldn't be affected at all, due to while there are relatively significant populations there, they just don't get much in the way of visitors, and by the time an outbreak begins these places could get enough word to sela themselves off. Take my hometown of Lubbock, Texas for instance. I mean, its a town of 250,000 people, and while it has an airport, it doesn't get much action, and there isn't anything besides little hackdirt clusters of 10-12 buildings called townships anywhere for about 50 miles in any direction. The closest city to it is Amarillo to the north, which is even more removed.
The argument of course is that it only takes one zombie to destroy and infect an entire populace, but if they get word they can immediately begin screening anyone who comes by air, and after a while the entire airline system would be shut down entirely. My point is, what kind of delivery system would it take to make sure that these pockets of humanity are totally wiped out so that only a tiny number of people would be left to survive? Jeez, I'm sick.
