These are some cool bunkers, but it reminds me of an article from a few years back, maybe from HN? An expat had a nice house in some Central American country back in the 70s or 80s when there was a coup with a lot of rioting and looting of the more well-off. Some people start freaking out, grabbing golf clubs and such, but the owner is able to get in touch with his army friend who just sends a jeep with a 50 cal and a couple soldiers to park near his house. He wasn't looted.

It seems like these sort of connections will matter more in a doomsday situation than how deep your bunker is. How do these people living in various states plan on even getting to their bunkers in Kansas if the "shit hits the fan", as they say? I think a fair benchmark is Mexico today, where it isn't safe to drive between many cities at night, and on some roads during the day. Not like, "you might hit a deer", but "you might hit a cartel roadblock and be robbed, raped, or murdered". And everybody already knows approximately where the bunkers are. These people had better plan on getting their timing exactly right, or they'd be in for the same.
