The topography of the built environment is in a constant state of change, but the rate of that change is usually so slow that we don't notice. Until we observe that what was once a park has evolved into a strip mall while we were on vacation, or what was once tennis courts for adults has become a playground for children. I think it is the in between states that are the most interesting from a photographic point of view. Anyway, I still cannot figure out what is going on here, I just see a great deal of dirt being moved around. But I know for certain that the landscape will never look exactly like this again.
