Dripping faucets are a wasteful nuisance, but as this video shows, dripping fire hydrants are much, much worse. This video taken on Nelson Avenue in the Bronx shows how in this cold weather, a small leak over time can coat a large part of the street in ice. It’s rather fascinating (and dangerous).

There’s a bigger story to this than just the video, however: the cameraman is Matt Green of I’m Just Walkin’. His goal is to walk every street of NYC. The New York Times wrote about him last March. As of now, he’s walked for 392 days. That’s dedication.
