Now I know what to do with all those Y2K buckets of dehydrated celery my nieghbors tossed out. And speaking of Y2K, lets consider the premise of "bugging out." Sorry, but the whole implosion of society and Walter Mitty, Burt Gummer, Mad Max and the alumni of Survivor fleeing Los Angeles for time share cabins in Big Sur; encuring fire fights, midnight emergency surgery by maglite and jerking road kill racoons is to much. The biggest social upheaval in the USA was the Great Depression. More people were out of work, on the road and improvising than our survivalist's wildest post apocalyptic fantasies. Their history, and what they think of modern worries is out there; in libraries, film documentaries, Stienbeck novels, train museums ( listen to a bonafied Hobo talk about the difference in road people then and today,) and most important , our own grandparents. As for cache's? I did it once during a desert excavation. Mostly water and a few goodies stashed along future survey routes. It was clearly marked and noted it could be used for emergencies , but please leave it there. One day two ladies from Iowa drove up to see the 'dinosaur diggers' and produced one of my stashes from the Oldsmobile's trunk. "Look what we found! Do you think it belongs to anybody?"
