Anybody know of any resources that I might be missing for this (aside from above-mentioned Census site)? I need something that I can print out or copy and then mark up to define boundaries. Hell ... I don't even actually "need" this, but we're trying to get a handle on "who is where" so we can have a better fix on why we're having to carry such a big load on some co-op projects.
Damn ... this is one information thing that was easier/cheaper to get before the Web came along. Heck, they're not even publishing the old zip code annuals (which did have pretty decent maps) anymore (it looks like the last one from Rand McNally was from 1998!).
