It is a perfect spot. It is isolated and no zombie would think someone would camp out in this area. You have space to load up weapons plus you can stock on food. It is not very populated so it will not attract flesh eating creatures.
This can be a good hideout for a couple of days. Cameras can be very helpful since you can monitor if the zombies are around. Entrances of banks are strong and are sealed electronically. This can help you keep the zombies out.
