Arlington's Smart Growth Journey is a documentary movie chronicling the transformation of Arlington to become a liveable, walkable communities. Arlington didn't get to transform itself into smart growth communities just like that. There's lot of politics, citizen involmentment, etc. to make it happen. If you look at the timeline that shows the county's smart growth throughout the decades, you'll see that it took more than 30 years in the making. (So, don't feel bad with Dulles Metrorail project - phase 1 - that won't get done until 2013).
