Unfortunately a lot of plans such as flying to a Scottish castle, building a fortress or moving to the top of a tepui (http://www.terebess.hu/kert/roraima.jpg), may be a touch impractical. I've had to create a back up plan where we have very little time to prepare. Now, I live in a town of 15,000 people, an hour east is a million people. The hypothetical scenario is as such: The city has been infected, it will starts spreading towards the town and it looks like it wont stop spreading anytime soon.
