5 different sites that are 1970's nuclear second-strike anti-ballistic missile sites in N.Dakota, up to 400 acres+ including 5 level bunkers, above ground buildings etc.
Obviously a bit far to bug-out to
Probably mostly flooded and with various environmental issues, but still it's fun to dream about an ultimate zombie bunker
