What is considered small? Our local offices have parking for 40+ and fenced in areas for twice as many postal vehicles. There are and never has been any type of security, detectors and many do not even have the firearm restriction posters at these branches. If the gun restrictions are there they may be on a bulletin board in the PO box areas. I usually don't go to that area. There are no larger facilities locally that I have seen. These local PO's serve a population of 150k+.
