Cheyenne is located in Wyoming.
Post apocalypse Edit
The Westward-bound survivor group encounter the town in search of Murphy.
The town seem free from fallout from the nuclear blast.
It's where Murphy hides out after the nukes fall over Colorado and the rest of the US. He moves in to an abandoned Strip club where he spends his days practicing his "zombie wispers" on the zombiefied strippers and costumers.
After Cassandra finds him he brings her with him there.
