No experience with NYPD auxiliaries but I am one down here in Virginia. We went up to NYC to the NYPD Auxiliary Memorial Service a couple months ago so I got to chat with some of them. From what I heard, there are A LOT of Auxiliaries on the books but not nearly as much that actually show up and do their work, so you probably have an opportunity to stand out. They have their own cruisers and lots of different jobs, some of the higher ranking members are armed. They were completely mobilized during the recent city wide blackout. In the precincts they have their own chain of command up to Lt or Capt (I think). Plenty of opportunity to do some work and get some experience. There are some NYPD people on this board (some say they should get their own ;)) so they can probably give you the inside scoop.
