In my garage I have 9 metal security doors, and all the fittings have already been placed on all my doorways INSIDE my house...

I have already installed studs(dont know what to call them...Im not a fucking carpenter) on all my windows, and have heavy plywood, with custom lug locks (like car rims) for all my windows...

In the event something super shitty happens...I install all the security doors inside my house and make it a home invasion nightmare, and yea...all my windows are non accessible unless you happen to be car thieves with multiple lug lock extensions for a drill...

I had someone install both a floor door to the crawl space under my house, and a roof hatch next to my attic access.

I had a ground water pump put in 10 yrs ago, thats overgrown by a shrub I planted, has a lock on it, and is weatherized, and used frequently to insure usability.

Many other things..I wont go into...

Best course of action someone could do is try to burn me out, but I have treated the roof and sidings for that...

Long story short...Im WAY TOO MUCH EFFORT to try and invade or ransack...better be moving on to the house next door!
