Someone recently pointed me to the iron fence that surrounds the D train station at 9th avenue and 39th street. I had not noticed before then that that the gate and the fence had a bee motif and that the gates had been made to look like honeycombs riddled with Bees. The installation apparently dates back to 2012 and the station attendants weren't even aware that it was there. The artist Christopher Russel has some fine pictures of it at his website. Most users of the train probably haven't noticed it either as the rush to the station to catch the train. The New York Times did a writeup on the gates when they were put up. If you haven't seen them or were unaware they were there you can visit the station and take a look.
