Bugging in, 7-8. Plenty of food, water, generator, gas, first-aid supplies.
Bugging out, 4. Living in Brooklyn, just getting out would be a major undertaking in any SHTF situation. Three million people, three bridges and one tunnel. I have a bugout kit with 5 days supplies, and a cabin about 100 miles from the city. Not much in the way of supplies there though. Can't get the family interested in spending the money it would take.
We also have a sailboat, but getting to it from home or work would require traveling across parts of Brooklyn you wouldn't want to be in even during normal times.
The Gowanus canal is about three blocks from my home, so I should probably start working on a plan where I have a small raft or boat that can travel under the draw bridges, then we could take that boat out into the harbor and reach the sailboat that way.
