My office window overlooks ground zero, so I get a daily reminder to be prepared. I'm within walking distance of home, as long as the bridges over the Hudson aren't the target.

In the office:

Crank radio
A dozen N-95 masks
Liter of water (we also have the five gallon water dispensers)
Three or four heater meals
Assorted snacks and comfort food
Pair of old hiking boots
Flashlight

On my person (and in my bag):

Small FAK
Flashlight and extra batteries
Nitrile gloves
Emergency blanket
99 cent rain poncho
Map of the city
SAK
Tea bags and instant coffee
2-3 protein bars
Hand sanitizer
NATO matches
Two bandanas
Two N-95 masks
