Today, April 1, 2012 is Theme Day across the CDP(citydailyphoto) community. When you think cobblestones in this city you think Wharf Street. Along with cobblestones, you better think feet, because most hours it's open only to foot traffic. So don't be a 'fool' and do something foolish with a car. I can hear Dusty Springfield's version of Walk On By echoing in the back of my head right now.
