Most of the photos I take for the Atlanta Proximity project are taken within the "perimeter" of I-285. Atlantans spend a lot of time thinking about the perimeter, comparing ITP (inside the perimeter) to OTP (outside). But I-285 isn't the only perimeter that should interest us as Atlantans.

Watersheds are another example of a type of perimeter.
