Or some other year, doesn't matter. Humanity has been primarily destroyed by some catastrophic event. Be it a flu nuclear war, shifting of the poles, or some mystical occurrence, either way 99.9 percent of people are gone, leaving about 1 in 1000. In a small town you might very well be alone. In a large city other survivors will be around, but it's unlikely you know any. Where do you go first? What do you do first? What happens to humanity?
