The empty cityscapes are cool; but we also need somebody to be compiling blue sky photos, mountains in the distance from cities that haven’t seen them in years, Catalina from Wilshire Grand Center, Beijing with no smog as seen from a tall building, something from the top floor of the Sears Tower, etc.
Just to be able to point to a huge mural of a bunch of these pics, and say “that’s why we want to switch from fossil-fuel to solar/wind.”
