This week’s barrage of snow and ice has made sneckdown spotting an international pastime. We may never look at slush piles the same way again.

Here are some examples of nature’s traffic-calming from the past few days. Also, a shout-out to sneckdown spotters in Chicago, Cambridge, Philadelphia, Pittsburgh, Carrboro, and Edmunton. And in case you missed it, here’s a vintage shot courtesy of @BikeGirlNYC.
