The Seattle Times focuses on some folks who are abandoning the suburbs of Seattle for the city itself. My family has made the same choice, opting to be in the city rather than the 'burbs this time around. That's partly a lifestyle choice (we detest the barren 'burbs), and partly a choice mandated by environmental concern.
It's great to see people fleeing the suburbs. I want to see city neighborhoods become all-inclusive enclaves again. That said, there are other alternatives to the new reality of expensive oil, including 4-day work weeks and telecommuting. Moving is under the control of the individual employee; 4-day work weeks and telecommuting are options that businesses must be pressed to support.
In the end, all three strategies will do more than just save gas: by shaving time off of our commutes and giving us more time at home, they provide the opportunity for us to build community and strengthen our families. Aren't those goals that politicians on both sides of the political spectrum could support?
