Has anyone tried to theorize how Dharma can successfully hide the building of the Swan Station from the Hostiles? Ever since Dr. Chang opened a (poorly) 'hidden' gate covered with vegetation that led to the future location of the Swan, I have been questioning the writers more and more. The Hostiles have been introduced as a group of very island-protective people who can appear almost out of nowhere to kill/hold people at gunpoint. How do they not hear the loud noises of backhoes, jackhammers, drills, crew members yelling at each other, etc.? A FENCE is going to stop them? Whats the deal?
