The problem is that Atlanta's built environment is literally the textbook example of tastelessness and inefficiency. "City" is a loose term for a centerless amalgamation of car-centric sprawl.
As learned from relatives living there, Altanta's long-term water situation kinda frightens me. Their aquifer (aka Lake Lanier) can't sustain the anticipated population, and it looks like fights are brewing with downstream parties like Florida, who also have legal share of that water.
