Please give us the list.
One flashlight, LED bulb I like the kind that you can strap to your head.
One floppy hat.
One waterproof container of "Strike anywhere matches"
One pack of fire-starters. You can make your own out of dryer lint and wax or just buy a pack.
One 36" X 36" square of heavy duty aluminum foil. This can be used as a reflector, something to boil water in, something to store food in or a signal.
One candle in a can.
50' of para cord.
Insect repellent (Yes even in the city!)
One tube of lip balm.
One set of socks.
One set of drawers.
One T-shirt. Heavy duty and over sized.
One bandanna. Bright. Some color that stands out.
Pack the four items above in a one gallon, heavy duty ziplock bag. I add in a few packets of salt, sugar and some tea bags.
One police whistle. (much easier then screaming)
Water purification tablets.
MPI Emergency space bag.
MPI emergency space blanket.
Metal water bottle.
First aid kit. (sterile dressing, ace bandage, butterfly bandages, duct tape, Bacitracin, tweezers, safety pins, needle and dental floss.) I also add a few tablets of tylenol. This is for comfort, not survival. However I always include aspirin and Benadryl, one tablet of each will take an allergic reaction down to survivable level.
Tube tent. Bright. Some color not found commonly in nature.
Signal Mirror.
You can add a couple of energy bars. A washcloth and small bar of soap is also handy.
You might notice that I don't include fishing gear or anything like that. You are not camping, only trying to stay alive until you are found. The contents of this pack along with some water will keep you alive for at least a week.
