Recently I was hanging out downtown and heard an interesting story over beer. It happens to be that the Green Line has achieved, for some, the ultimate. There are people living in Clackamas that have gone car free by choice! Truly amazing, America is slowly evolving past addiction. It is slow going, but it is starting to grow. Watching this ground swell of change is amazing.
To note, this could have happened with the bus lines, but it was however much less likely. Light rail enables and encourages people to drop their cars and focus on livability in ways that buses cannot and will never achieve. Buses are important, but they are not agents of change.
