Yesterday we promised to reveal a very special urban planning-related surprise. Unfortunately, we can't tell you what it is quite yet— yes, we're breaking our vows, but we're working diligently toward a Wednesday reveal. Architects, planners, and novitiates alike, firmly affix your designer eye wear, because it's about to get serious around here. We're talking creativity, personal sacrifice . . . and a hunk of cash for your kind efforts.
