"10 Towns that Changed America": Airing tonight (Tuesday, 4/19) at 8:00 on PBS

This is a DVR alert for all you planning folks, the PBS segment airing at 8:00:

"10 Towns that Changed America focuses on ten 'experimental' towns that did not evolve organically over time, but instead were designed (or redesigned) from the ground up by visionary architects, corporations, and citizens, who sought to change the lives of residents using architecture, design, and urban planning. Some of these visionaries were driven by an ideology, others were trying to serve their own financial interests, but all had one thing in common: they believed in the power of our built environment to change the way we live."
