I think its really interesting to see parking lots/vacant land and the damage that was done to American cities. I have been tracing them here lately and trying to get a consensus on what cities are and are not damaged the most by downtown parking.
Each time I make a new one Ill add it to this first post.
Houston, on the left side of the highway, theres tons of vacant lots and parking lots, but it got too detailed so I gave up.
Dallas
Boston
Not a major US city, Little Rock, but it kept me sane while living in Arkansas.
Cleveland, May 2010
Tulsa
Portland
Denver
Austin, included in this one are also the parking garages that mar the city.
