Walking is the best way to get to know a new place. It's environmentally friendly, healthy, but best of all, its slow. Walking allows you time to soak in so much more of the new place you're in; from the faces, to the buildings, to the nature. In a big city like San Francisco, I love finding nature among all the concrete. There's so many hidden city gardens and bright walls juxtaposed with even brighter flowers, that you would miss in any other kind of transit.
