Let's Play a Zombie Survival Game, Week 2

I am going to give you a list of 4 items.  You will need to put these in order of importance and defend your order (this can be done in the comments here or on Facebook).  I will reveal the proper order and why at 6:00 pm MST Monday.

Anyone who participates in the game will have a chance to win a pdf copy of Life After the Undead, Death to the Undead, or Finding Eden.  You will also be put into the drawing for the grand prize of a Zombie Survival Kit.  This particular game will be played on five separate Sundays.

Good luck!  Have fun!

The 4 items:

Handgun/ammunition
Canned Food/Can Opener
Long-sleeved Shirt and Pants
