E-Pics - inside locations in NYC? (xpost)

So my e-pics are this Thurs and it's the third time I've had to reschedule because of weather. I've decided I'm going to take them either way on Thurs. We are planning on doing them over by the Brooklyn Bridge but I want to have a backup in case the weather isn't good. Does anyone have any suggestions indoors either in Brooklyn or NYC?? The only place I can think of is Grand Central Station. Anywhere else????

TIA!!!

-Brooklyn Museum of Art (may need a permit)
-MTA Transportation Museum in bklyn (it's in a old closed station, and along the 'track' are these amazing old subway cars from the 1900's up to the 1980s) - plus it's usually pretty empty!
-Under the bridges of central park
