Walking in Kalemegdan Park a week or so ago, I came across a group of masons repairing one of the fortress's huge brick walls. I lingered, hoping to sneak a shot, when the fellow on the left saw me. He waved and said, "Take my photo!" and then called his buddy over, too. Once again I promised them a photo, which I've since taken to them, and they were happy!
