One of my highlights of the weekend is spending time on Sunday selecting produce for the week at the Heart of the City Farmer's Market. Located in the Tenderloin neighborhood of San Francisco, you're always ensured a grand mixture of fun, crazy, and just plain weird. Without fail, there are always a few musicians around. It can range from young guys on a honky tonk piano and drum set, to a classical cellist, to an old man on a 2-stringed Chinese violin playing Jingle Bells. It's pure bliss.
