Just about any major city will have an intelligence office of some kind.

I'm pretty sure the NSA has better ciphers for phones than poorly coded ASCII. Isn't there an art installation at the NSA that still hasn't been cracked after 20 years?

You're thinking of the Kryptos sculpture, which is at CIA headquarters in Langley, Virginia (http://en.wikipedia.org/wiki/Kryptos); "of the four messages, three have been solved"; it was installed in November 1990, so it's been almost 22 years.
