Quick question! Where is the Holding Compound located, geographically? Is it within a UE population area, or a wastelandish area, or...?

I ask because for the mission Chrys's back-in-time group is gonna be staying in the area for at least a week or more, so it'd be good to get a general idea of what they could find in terms of food and shelter during the daytime, since I'm assuming they don't get to trip back and forth until they're done with the job.
