Mr. Selfish and I love living in cities where you can walk. Not only is it great exercise, but you don’t have to look for parking. Being in Nob Hill, we have taken to walking to the Ferry Building on the weekends. The walk is about 1.5 miles one-way and takes about half an hour at a leisurely pace through Chinatown. We usually go on Saturdays because we enjoy browsing the farmer’s market and tasting all of the delicious samples.
