Yesterday I walked once again from the Wiehle Metro station to my car in a parking lot four miles away. Why is this worth mentioning? Only for this — that I am, finally, commuting on foot in the suburbs.

This is not an accomplishment to be shrugged off. And I don’t mean it’s my own personal accomplishment but an evolution in the way we live. That I can step off the train and travel on my own steam to the next destination is a marvel, given the way I started living here 25 years ago.

Then I couldn’t leave the neighborhood on foot because of cars barreling down narrow, un-shouldered roads. Now sidewalks and bike lanes take me to the grocery store and pharmacy; let me tap into Reston’s trail system, which used to be a tantalizing but unreachable distance away.

So to all forms of walking I celebrate here  — ambling meditatively through the woods, running pell-mell through the meadow, strolling briskly through the city — let me add the walk which is not a destination in itself but which has a larger purpose. It not only takes me out of myself; it takes me home.
