There's lots of good lore about stuff like this in phreaker circles. I remember a story about someone who supposedly found some listings of 710 numbers including things like the presidents bunker and such. The folks answering the phones for some of these numbers were not amused and were also caught off guard by calls from kids asking to talk to the president and such.
