Russian suitcase nuke planted under the house. Rigged to a dead man's switch, carried clinched in one of my fists at all times. Flaming oil jets covering the front porch, and three rear doors, none of which are real. I usually enter or exit through a tunnel I dug over into the neighbor's basement. Caltrops randomly sprinkled on my yard, and that of all neighbors within a one block radius, which makes lawn maintenance quite the adventure. I've got some L9 anti-tank mines that I plan on laying across the subdivision's busy intersections/avenues of approach, then I think I'm good.
Darn it. I forgot to buy a gun. I hear good things about .22 LR as an SD round. Opinions?
