Sewer system map?

[Wippit Guud]

Anyone got one? I'm running an 'after armegeddon' campaign, and the party has stumbled upon a buried city (like Pompeii), where the majority of dwelling are now underground. The city has an old sewer system which is used as roads, but the layout would be vastly different than streets.

Just wondered if anyone had a map resourse for something like this.

Try here http://www.wizards.com/dnd/article.asp?x=dnd/mw/mw20020131b Also there are some collection of Maps available in books at Gamestores. I can't remember who published them, but they're good and generic. The title I remember are "City Maps" and "wilderness Maps" but don't quote me... I was poor at the time and didn't buy them. Hope that helps.
