On my day-long trip to Amsterdam, part of my Great 2012 Mileage Run, I left the hotel and wandered around for hours on end. This winter was the coldest in Amsterdam in the last 15 years, and the first time that some of the canals froze completely over, though that happened right after I left. As soon as I made it back to New York, I saw news articles and videos with people walking across the canals on the ice, not a normal sight! I took a photo of these swans that flocked to this one section of this canal, which was slightly odd, as the rest of the canals I came across had a swan here, a duck there. This was a dense gathering, and many others around me took similar shots at the time.
