Anyone who lives in a city will know the feeling of having been there too long. The gorge-vision that the streets imprint on us, the sense of blockage, the longing for surfaces other than glass, brick, concrete and tarmac....I have lived in Cambridge on and off for a decade, and I imagine I will continue to do so for years to come. And for as long as I stay here, I know I will have to also get to the wild places.
