My house is no more than a cardboard box. I haven’t bought them yet but I’m still planning on using hundreds of bags in stratigic locations within the house and on the hill. Since I can’t run very fast or far anymore, I figure I better have some other advantages. A force multiplier in the lexicon of the military minded. Even a relatively small bunker positioned properly within your house could give you the upper hand.
Remove cover outside or use it for traps.
