While stripping the interior out of my wife's '72 GTO a couple of years back, I found a map from 1969 buried under the seats, it's pretty interesting to see the differences. Here's the map scanned, the basic residential areas overlayed on a 2010 map, and the scanned map file if you want to peruse the map (just right click saving the JPG doesn't keep the street names very clear)
Population 1969: 370,000
Population 2010: 988,000
