I really Implore you to walk around and explore the map as much as you can. This game has many unique locations outside of the areas the main quest locations the game takes you. Many locations have random quest to encounter and great enviormental story telling its so immersive. Also explore the museum of History some more there is a lot there.
its crazy that i finished fallout 3 without knowing, nor using the flashlight from the pipboy, i only found out about the damn thing in new vegas, good god.
