There should always be a lookout stationed at a high point around your survival retreat or stronghold 24/7, and I would suggest assigning regular shifts to accomplish this. It might be tempting to put one or two people who are the best suited to something like this and leave it at that, but the longer a person is on this type of duty the more likely they are to become complacent and miss things. Likewise, it will be important to assign shifts for walking the walls of your community, if you happen to be lucky enough to have them, or at minimum to patrol the perimeter of whatever holdings happen to be under your control and protection. These individuals need to be looking for any possible security breaches, such as individuals climbing over the walls, as well as watching for outsiders in case they be hostile. As Rick states in this episode, "People are the real threat now," and it is nothing but wisdom for you to understand that is how it would be in the real world as well in the event of any type of prolonged emergency. Rick understands completely just how lucky the people of the Alexandria community have been thus far as well as just how unlikely it is that such luck will continue to last without proper security being maintained.
This type of thinking is actually something I've talked about quite a bit under the generic umbrella of what I refer to as Medieval Survivalism, which can be quickly described as an ideal of survival that revolves around a stronghold, rather than either a "bug-out" mentality or the standard Prepper wisdom of trying to lay low and stay more out of sight. YMMV, but I firmly believe it is a philosophy that lends itself better to a long-term mode of survival, centered on community.
*** SKIP THIS PARAGRAPH TO AVOID MILD SPOILER *** Daryl seems to be having a hard time re-acclimating himself to normal society, and a stark analogy can be drawn between him and the situation involving the horse from this episode. The point to be taken is that the negative events which occurred (I'm trying to keep the Spoiler mild by not saying exactly what happens) resulted from the attempt to help the horse by redomesticating it. The conclusion that Daryl is pretty clearly drawing from the whole situation revolves around the fact that the horse seems to have been better off when it was wild and untamed, only coming into danger when they got involved and tried to bring it back into society per se. This will truly make it more difficult for him to allow himself to become comfortable within the seemingly protective walls of the Alexandria Safe Zone (of course, this episode also laid out the beginnings of an arrangement that might allow him to ease his way into the community without having to fully give up his instincts about being out in the wild). And, truly, the part of him that is hesitant to get comfortable may very well be wisdom speaking. In fact, I would argue that it is. The survival instinct can be a very strong protector, and the group of characters followed by this program have been forced to develop a very strong such instinct. If they allow that instinct to become complacent, it could definitely lead to tragedy, so I would always advise a healthy level of readiness and training to keep oneself sharp.
