This is a town with several individual location markers like Corvega Assembly Plant, Super-Duper Mart, and Lexington Apartments, to name a few. There are also a lot of ghouls in the area and the plaza near Super-Duper Mart is a known behemoth spawn location as well. In the street NW of the Lexington Apartment, there's a Pulowski Nuclear Shelter there with a mini-nuke inside.
There’s a military train directly west of Lexington with an incomplete Power Armor set inside a cage. You need to hack the Advanced Terminal nearby to unlock it.
