Defense question... If you rebuild the perimeter fence around Sanctuary, and you place gates in various places, do the gates need defenses? I see that my citizens often open a gate to conduct some sort of business but then do not close it. So, I figured I needed to place an observation post as well as maybe some turrets. Feedback is welcome. BTW... I did have a small Raider attack at the bridge. Apparently they were following the traveling vendor. Otherwise, it's been all quiet.
