Have you ever tried to drive around Boston? It’s nearly impossible to navigate the narrow, winding streets that meet at odd angles, curve back around, and join in traffic circles that you find almost nowhere else in the country. Why would any city knowingly design its streets in a fashion nearly impossible to navigate? Well, there’s an old story, perhaps apocryphal, that the streets follow the old cow paths from the days when the Boston Commons was a cow pasture hundreds of years ago.
