I wonder how many of these bunkers exist and how many have been abandoned over the decades. I bet that was a sight, pretty easy to get turned around down there. If all those people knew about this guys shelter over the years and the SHTF that place would have been swarmed by people who didnt have the sense to prepare and/or were laughing at him while he was planning. Kinda scary, having to fight off and turn away masses of scared pottentially dangerous people. Looks like imo his 18 year plan was comprimised and I would definitly form a backup plan.
