I know a lot of you on here are or are working on being prepared with water, food, munitions ect ect.
What have you done to fortify the home for bugging in. I have been thinking about gettign some 3/4 ply when I see it on sale for lower level windows ect. Now I know its not going to stop rounds from coming in but it will block line of sight and they wont be able to kick the glass out and climb in.
What do you think would be best after I cut it to size for each window. I was thinking 3" deck screws, but if the power is out and my cordless is dead how an I gonna drive 100 3" screws by hand

Looks like good ole hammer and nails
I don't rally want to drill my window cases for a possible problem that may never arise, but I dont want to be caught with my pants down either.
What else have you done or what else are some good things to think about and plan for to fortify the castle.
