At the beginning of the text, Dennis, Mac, Jeremiah, and Anna are heading towards Petey Coltrain's radio station.
We can arrive at this answer because:
"End of the Road," tells the story of a group of friends who end up being chased by a group of zombies.
They start the story by trying to reach a radio station.
One of these friends, Anna, is attacked by zombies and ends up being bitten by them.
Anna progressively becomes a zombie after the attack. Her friends are very scared of her, as they know that zombies are irrational and violent. However, Jeremiah decides to continue having contact with her while she is still human.
