When people retreat to the safety of their underground bunkers, are they going to take all the heavy construction equipment down there with them too? Or leave it on the surface?
So, what's to prevent anyone from just digging those bunkers right the fuck up out of the ground? Bunkers are going to be stocked full of supplies that desperate people are going to be wanting.
Or if someone's feeling particularly mean, and decides they don't need what you have in storage, or decides people like you are to blame for the SHTF situation they're now in...what's to prevent anyone from just parking a tread of a 140-ton monster on top of the bunker's exit door, and leaving it there? Good luck getting that door open!
