This location is a small settlement built around a huge monument. Within the enclosed area, you find all of the traders that you need, the doctor, hotel and you will also take several side quests.
In front of the main building, you will be accosted by Edward, who will task you with quest Special Delivery.
In the front of the building, there is a girl named Meg, who can give you a tour around the settlement, for 10 caps. Unfortunately, she limits her tour to uttering a single sentence, in which she tells you where to find what.
Atop the monument (you can climb the stairs there), you find an issue of Live&Love.
Inside the big white building, you meet two traders - Deb and Lucas Miller. They both sell weapons, armors and ammo.
Outside, at the counter, you meet two more traders. From Tony Savoldi, you can rent a room for 10 caps and you can barter with him (he offers junk, mainly). Joe will task you with a short quest to find his family member and he will barter with you (he offers food and meds).
In the Southern part of the settlement, you meet Kay, who is the local doctor. She can heal you and cure you, if you are irradiated (for a price, that is). You can also barter with her.
