A big destroyed building. Around the building, you can find a friendly robot. Inside, there is nothing of interest, apart from some meds and some ammo.
Opposite the building, there is a Red Rocket gas station. Watch out for the super mutant lurking around here. Inside, you find several various workbenches.
While you are at the gas station, it can be attacked by a group of super mutants with a legendary one as the leader. It is best to backtrack into safety then. Also, you can use the robot's presence to your advantage, who will help you in fight. If you can defeat them, you can loot the corpse of the leader for one of the best weapons in the game.
