In fact, it's crawling with lawless Raiders who would love to kill you and take everything you have. When you arrive outside of the large building, take it slowly and try to use as much cover as you can going forward. Nonetheless, when you start approaching the location of the building, buckle down, slow your movements, and get ready for possible combat. If you run into any enemies (which is unlikely, especially if you're traveling during the daylight hours), they'll likely be simplistic beasts to kill. Simply keep your gun drawn as you go, and be sure to utilize your map via the Pip-Boy 3000, since after talking to Moira, the location of the structure should be marked on your nebulous map. You'll have to go there on foot, which shouldn't be much of an issue, especially during the day.
The first task she'll give you is to travel to the Super-Duper Mart, which is due east of Megaton. The latter really makes the whole ordeal worth it without her prizes. In return, she'll reward you with various goods, and what's more, the experience earned from the events is substantial. She'll give you a series of sequential tasks to perform, each of which adding to the knowledge stored up for her book. Upon your first meeting with Moira Brown at Craterside Supply in Megaton, you'll get an offer to help her with necessary research for her yet-unpublished survival guide that she intends to release in the future.
