Hat tip to @zacfrank for this shot of the new CityRack, the first of its kind to be mass-produced and installed on a New York City sidewalk. After the "hoop" won the CityRack design competition last fall, DOT announced that it will install 5,000 of them in the next three years. Where is this one exactly? After a bit of sleuthing, I still don’t know. The sleuthing was pretty cursory, I admit. If you’re heading out for Summer Streets tomorrow (forecast: totally gorgeous), perhaps you’ll stumble across it.
