From Michael Muni:
A complete list of supplies you will need in case of a hurricane. Includes things you will need before, during and after the storm. Includes item descriptions and pictures. You can find hurricane supply lists from many places like your local grocery store or even online. The problem is that they are all different and have a very small list of item. What we have done is reviewed hundreds of supply lists and come up with a complete list of everything you will need to be ready for a hurricane. Just check off items as you get them to make keeping track of your supplies a cinch.
