Natick Labs, Sudbury Annex
Once bustling, now closed and appears to be abandoned. The WWII style building is in decent condition but the area is overgrown. All fenced off. Military housing area just down the road is still for the most part occupied but has an odd aura about it. Private cars and playgrounds but no one was visible and not a sound was heard. Reminiscent of a Twilight Zone episode.
