Photodocumentation of post SHTF...

Something I've been stockpiling along with all the other gear is photo chemicals, paper and film... as well as an army of Pentax Spotmatics. I was trained as a photographer and have always believed that the "old" ways of making photographs might come back into fashion if ever the digi world fails. I figure it might well be someone's responsibility to document the events of a post SHTF scenario. I have also picked up a few wind-up 8mm movie cameras, but they will need some work. Anyone else out there have any ideas on how to best go about the job of documentation?
