Three cheers KC Gridlock!!! Your quality of work never ceases to amaze me.
What I also love from your photos is that you capture the density of the CBDs, not just the skyscrapers.... It makes for some very unique comparisons. For instance, in this section, if I were to rank what I can see, then density of the cities would be as follows...
1) New York
2) Philly
3) Oakland
4) New Orleans
5) Portland
6) Pittsburg
7) Nashville (etc.)
