No that's a great idea. I had an idea to make a big map of LCN territory, one color for each family with a key on the side. My idea was the whole country. NYC would be dashed lines of each five families colors the more interesting aspect would be blips on areas you wouldn't expect, like WV for Pittsburgh or a colored square highlighting a town a made man ran a group out of. And eventually we could fill it out with precision. The problem is the LCN world is ever changing and a map of current OC wouldn't would be less diverse and fleshed out than a traditional map from the mob's heyday so my idea kind of stopped there. But I think a neighborhood map is really viable if anyone has graphical ability. Maybe there's some interest?
