When I lived in Rockland, Massachusetts, I frequented parks such as Wompatuck State Park and Bare Cove. They were both popular places to walk dogs, run and ride bikes, but always had an unusual feel to them. I knew they were both sites used by the military. It just seemed unusual to me that land that was once severely off limits to the public were now free to roam. Even odder was the presence of tangible pieces of the past such as powerlines, fire hydrants and old roads. The most striking was the bunkers and other actual structures that could still be seen at Wompatuck.
