Rockbreaker's Last Gas

Rockbreaker's Last Gas
The Rockbreaker's Last Gas is a ruined gas station in the western Capital Wasteland. 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, where you can meet Uncle Leo for example.

You can usually find a Nuka-Cola Quantum on top of a Nuka-Cola machine inside the fenced area. Check around if it isn't there, as it might be on the ground for some reason.

If you are to the point where the Enclave is "setting up shop" around DC, then an Enclave Outpost will be located here.

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.

The rifle is in a locked (Very Hard) locker, Lockpick 100 required. Or, if you have a follower, he or she will steal it from the locker and kill the Radroaches (Fluffy and Jitters) in the cage with it. Don't kill Fluffy and Jitters, allow your partner to kill them or this wont work. Afterward, you can trade equipment and take the Victory Rifle from them.

There is a copy of Dean's Electronics hidden in a wooden box under the Workbench, and a copy of Guns and Bullets on the table left of the locker (in which the victory rifle is inside). You may find a Pre-War Book on top of it. Also there is a pack of Bobby Pins (14) on the table.

There is also a Stealth Boy in a slot of the first locker to your left when you enter the door.

In front of the entrance to the shack on the distant flat hill there is a landing zone of Enclave patrol.

Also on the Table next to the bed is 14 bobby pins i found very helpful
