I've been enjoying the threads regarding emergency kits/BOBs. But I'm curious if you all would recommend different items for a BOB that would be based in a large metropolitan area, like Manhattan. I live in northern New Jersey and most of my work is at what many consider prime terrorism targets (i.e. airports, tunnels, bridges, WTC, etc). I recently put together a BOB that I take everywhere with me. So far it consists of: bottled water, granola bars, first-aid kit, whistle, flashlight, knife, respirator w/extra cartdiges, gloves, rain suit, length of cord, roll of duct tape, and tissues. Any glaring omissions or useful tips would be greatly appreciated.
