I'd run to the building my dad works at. It's a Medicinal Factory and has several backup diesel generators that could power the whole plant for a week. Down that to only the newest building and you've got a month or so's worth of power. plus there isn't much in it yet and it has a huge warehouse inside of it. It has a state of the art air purification system in it too so that if there were any pathogens in the air, they'd only exist in the room for several seconds before they were sucked away. conveniently, it sucks away farts too.
Edit: I'd Drive to the building my dad works at.
