Thanks, Sarah.

Thanks, William.

Thanks, George. Am interesting idea about the urban desert. Downtown would be the urban jungle. Anyway, suburbs are deserted. In Toronto I couldn't walk a block without meeting people, but here I can walk for several blocks without meeting anyone. As I did on Sunday when I took this.

It's backstage, Bob. The population density is so low in the burbs that any litter or seems like a desecration of the utilitarian buildings. Downtown it's just a natural part of the environment.
