I am not precisely sure if this decay is urban or not, given the fact that I do not live in a city. The photos in question are of an abandoned sewage treatment plant on the outskirts of town though. Can I assume that overgrowth is okay?

Some of the more "textural" shots are slightly blurred because I was messing with my manual focus settings on my Canon Powershot A75.
Edit: As I can see, this would probably be more suited for rural_ruin, I am sorry to fill up space here.
