As a start you might look over the
lists of suggested contents that Doug has put up as what is in his kit. From there you could assemble on paper lists of what you think your modules should contain. This process will also help you think through what scenarios you wish to prepare for. Thinking about what you can live without in a given scenario will help you to determine what your different modules might need to be. Once you have lists of modules you might consider reducing redundancy in the modules where they will overlap because you will be carrying two or more modules at a time. Having pared it down to smallish module lists then see what size they will take up by going to REI or some other out-doors store which will have most of the items and see what you can stuff in what size pouch or box. Then if you have something that is reasonable in carry comfort and provides you with the correct "warm & fuzzy" prepared feeling leave the store without buying anything and assemble it at 1/2 or less the cost through the suggested links provided through this forum and web-site.
But first post your list of suggested modules here so we can let you know what you missed and completely destroy any warm and secure fuzzy feelings you might have developed. <img src="images/graemlins/wink.gif" alt="" />
