You and/or your group have set up a pretty sweet hideout. It's well stocked, pretty well fortified, and best of all, well hidden... So how do you keep it that way. And hopefully, in such a way that will allow you and/or your comrades to safely (of course safety is a relative term) enter and exit.
What are some good tips and strategies to use to either
#1 Keep the zeds distracted from your little hidey hole
#2 Trap the area in a way that either slows down or disables both the dead and unwanted living
#3 Keeps your place hidden
