Signs of the Infected

You wander for a few hours until you see something that looks familiar, the WELCOME TO BEMIDJI sign. You smile triumphantly. You made it. At the end of the main road, from the sign, you can see the grocery store logo. You start to make your way towards the store when you see a horde of zombies ahead of you. There are at least a dozen or more zombies in the horde.
You look around at your surroundings. All you see nearby is a gas station. How is that helpful? You wonder. But then you get an idea.

You have no weapons... and there's no other way to get to the grocery store except for going through the horde.
