I used to live in the Woolworth Bldg on Broadway in NYC. They had a very large bike corral in the rear of the building with an exit door to a side street. At the time, I had a Colnago that I loved more than life--no way was I leaving it in the corral (besides, the rear door didn't always close completely, rendering the bikes vulnerable). I became friends with the doorman, and he allowed me two privileges: 1. I was able to walk my bike thru the side door, avoiding the carousel doors, and 2. I was able to take my bike up the elevator and to my apartment. Not sure what the rules are today. [I heard that they are converting apartments to condos, with 7-figure prices for measly footage.]
No locks for me.
