Your friend is a man after my own heart. Sitting under my desk is a file box. It is affectionately known by a name I can't say here, but it is labled OSP. Inside is a number of manila envelopes. Each is labeled for a set of parameters. I know what is in there, but I will tear the right one open if the time comes, just becuase I know I "know" what is in there. Maps, check lists, that kind of thing. It gets updated every six months, or if I move. There is a red folder with maps of the various ways for me to get my folks. Yellow folder is for site B.

And every so often, I "sand table" the plans. I work out subplans for varous things like weather, people bailing out of suburbia, that kind of thing.
