I got thru the first 2 minutes. That's dumb. I'm sure a very smart future war lord has plans in place to raid them of their supplies. Wouldn't be hard!
No thank you, you store your stuff their but can't live their until shtf and who's to guarantee the security guards will let you in when the time comes. As Doc said, death trap.
Let me count the ways. If I wanted their stuff, simple, first I cut off the power from the wind turbine. Second if they have solar cut off that power. Third block off all the air intake vents. Or I could just pour some acid down the intake vents and wait. These are death traps.
