I work in mid-town Manhattan and sadly I have no game-plan for SHTF. No secret tunnel off this island and I don’t rate a helicopter, boat or blimp. What I guess I could do is run 40 flights of stairs down to the ground level (if the elevators aren’t working) and grab a six-pack of beer at the Duane Reade. I’ll then stagger up to Central Park and see how it all ends. If I don’t run out of cellphone battery, I’ll post a photo or two here.
Actually there is at least one tunnel that is a secret.
For only $75,000 per annum I can provide that information.
However you must provide your own transportation to the secure South Bronx compound and entry point, from there you can drive under the East River and emerge at another secure compound in Astoria, Queens.
Secure arms lockers for your personal weapons and other items can be arranged for an additional nominal fee, contingent upon your needs.
After that you are on your own.
