There's a fairly good program on the Histroy Channel that deals with hidden, secret, or built over cities and places all over the world.
I think the title is Cities of the Underworld or something.
There are plenty of places in the continental US that fit the bill, for the most part they are kept off limits though, mostly because of safety
hazards. However I'm sure if you find the places you could find some sort of guide.
Generally, there are a fair few cities out west that were abandoned when the gold dried up, most have been built over, or are maintained as historic
sites, or been redone for entertainment purposes.
Personally, ever since I've started reading the Dresden files I've wanted a look at underground Chicago. ^^;
Seriously, what's so hard about taking this seriously?
