Rockbreaker's Last Gas

Rockbreaker's Last Gas is a ruined gas station located in the western Capital Wasteland.

Location
It is located north of Everglow National Campground, south of Five Axles Rest Stop and east of Vault 87 and Broadcast Tower KT8. This area is also a random encounter area.

There is an Enclave outpost nearby if you have proceeded to that point in the main quest. If you visit before a certain point in the main story and then fast travel to this location, you'll be dropped into a swarm of Enclave troops; it's easier to travel nearby and approach on foot. The surrounding Super Mutants will engage in the battle as well.

Background
There is a short radio broadcast found called a CB radio conversation, and it implies the owners of the many trucks present were rallying here.

Notable loot
There is a Nuka-Cola Quantum on top of a Nuka-Cola machine inside the fenced area. Due to movements of NPCs and creatures, it may have been knocked over.

Abandoned Shack
In the abandoned shack at the top of a cliff to the west of Rockbreaker's is the 4th of the Keller Family Transcripts and the Victory Rifle, along with other some more loot and a couple of named radroaches.
