hmm, A main house, and a few outer houses, mostly like 2 bedroom houses, for people to live in. And a big fence around all of it, then a couple feet away from the fence, guard posts every half mile around the perimiter, Then about a mile away from all of that, a large wall, filled with water, like, a huge concreate wall with water in the middle, the water will be suspended in a mixture of saw dust, and sand, and it will be wet kind of like mud. in the middle of the wall, then around this wall every mile a guard tower inside the wall.
