> Deep Underground Military Base. The conspiracy threads recently talked about how the michigan meteor (predicted by anon) and the alaskan earthquake, were strikes on secret DUMB locations.
I've never put much stock in the DUMB stories. They would need workers to build, the excavated materials would have to go somewhere, they would need food and water and ventilation, there were always little green men in the stories, and people have gone out to the locations where they are supposed to be and they did not find anything to suggest there was an entrance there.
However, there are several cold-war era bases under mountains that were designed to keep the government going if DC got nuked. These are public knowledge, surrounded by fences and guards, real military bases. There were rumors that the staff at one of them was secretly running things behind GWB's back. People might apply the newer DUMB concept to these older bases.
