In the Delta Sonic thread the discussion seemed to be straying off course to a discussion that I think might be interesting...
Is commercial development always preferable over "undeveloped" land?
I say no.
I think that even in what are usually considered highly developed areas, an open parcel of land adds character, beauty, desirability and value to the neighborhood. Even in Amherst I've heard that commercial properties are required to have green elements... so someone must recognize the importance of non-development.
