New Bike Racks Popping Up All Over

Seems that these bike racks have appeared all over the place–as was noted yesterday, there are some on Coney Island Ave at Cortelyou, Emma says she saw some on CIA near Beverley, Marina saw some by the Tot Lot, and Liena noticed more in front of the Cortelyou Library as well as ones just across Cortelyou at Salahi Deli. Seen them anyplace else?
