I should NEVER have doubted you.
I remember it distinctly.
I was browsing through the video/DVD collection at the main branch of the NYPL when the lights went out.
In fact, it occurred only a few minutes after I had come up from the Bryant Park subway station.
Very, very hot.
The bathroom at the new Coliseum Books-which was just a block away from the library-was so crowded that they actually wound up closing it for repairs within the week.
