As I see it, the Minutemen (with our $150 per foot) can put up a lot of sections of fencing on the property owned by those who agree with us. What will that do?
THAT will encourage the invaders to infest the land of the unbelievers (water runs downhill) and increase those fools' unhappiness which will cause many of them to join us and request that fences be built on THEIR properties! Within a couple of years, the whole shebang should be protected, we don't need to keep them out, just delay them, then catch them with patrols.
I'm 100% for it. The Minutemen are awesome!
