Ha, good stuff. If you ever do something similar with the Portland area, I'd definitely be interested in taking a look at them for my own game.
My problem is that I'd like to make them "sourcebook" quality, with the correct fonts and everything. What I've done so far is use a series of road maps that I got for the PDX area, and I've been trying to edit them for my game. I'm wondering if I have to bite the bullet and buy Photoshop to do the kind of maps I I'm looking to do? I do have the kind of fonts used for the books, though. As it stands right now I'd like to map out every district of the Portland area like this and add stuff accordingly.
However, I do have a listing of all the neighborhoods with Security Ratings, some fluff history, key locations, major roads, demographics, government, things like that. Maybe I'll post that for now until I can figure out how to make the maps?
