The prinicipal defense for the inhabitants of Waller is an fence surrounding the central town. At night, this fence is electrified for protection. This is an understandable source of pride for the people of Waller, who often distinguish inhabitants of the Greater Waller Metropolitan Area as living either ITEF (Inside the Electric Fence) or OTEF (Outside the Electric Fence).
Waller also has a modest store of weapons for personal defense. These can be found in the Armory.
