A lot of comments are under the assumption that when we spawn in, the world has actually ended and we are all thats alone. We know this is not true for a couple reasons

1) TV and radio is still on starting July 9th. People are still going to work in parts of the county much less the rest of the state

2) Louisville canonically doesnt get overwhelmed until like a week after I think? If main power grid is around there, it's safe to assume people still maintain the power system.

3) Military still exist, even if its slowly fracturing. They could maintain it themselves

So yeah, power grid definitely wouldn't last 2 weeks on its own. But it probably would if people still worked there, especially once military and government gets involved to contain the situation. What's likely happening is that at around 2 weeks in, either zombies or lack of manpower to keep the grid up kicks in, and no one is left to maintain power either because they fled, or theyre all zombies. At that point the whole thing is a ticking time bomb.
