You’ll visit this zone as part of the Story Mission Sherman’s Camp is Crawling. The area has a Horde that roams it during the evening and Marauders can spawn here as well. There are three Nests and their exact Locations are shown below. You can tackle them in any order you want.
This Nest is inside the building. You have to enter through the window to find it inside one of the rooms.
Found in the same building as the first Nest, only in the second floor. You still have to climb in via an open window.
This is found inside a broken building near the visitor center where you can get the knife Addy needs for the Story Mission Sherman’s Camp is Crawling.
