What are some neat things to do/see in NYC that not all the tourists know about?

We're going for one night next weekend (memorial day weekend) and I expect there will be a ton of tourists there for this reason.



I'm looking for stuff other than the Empire state building and all that stuff, we've seen a lot of it.



So far I know we're going to the Lomography store and the Central Park garden (although tourists will probably be there).



Any ideas :)? Thanks!What are some neat things to do/see in NYC that not all the tourists know about?

There is a guide that gives some out of the way/unusual spots called "Not for Tourists". Maybe some things there you will find interesting.
