it just took me any easy hour to vote in Greenpoint, Brooklyn. I learned a couple of things in the process:
-know your voting district. the first line you encounter will probably be the information line to find out you district if you don't know it. if you know the district you can skip that line an go straight to district check in.
-at the district area there might be a couple of lines. one for checking in, which might be split in two alphabetically by last name. check to make sure you are in the right one.
-once you check in, you'll get a card with a number in the upper right. they may not be handed out sequentially. once you get in line, try to order yourself correctly with the people around you. you have to vote in numerical order, and if a number can't be found it causes 10 minutes of chaos and shouting.
-by the time you get there, people are probably going to be pretty testy. I found that figuring out the system and spreading the word to the friendlier seeming people around you helped things move better. (telling people what line to stand, etc.)
-remember, the only thing better than a casino fight is a poll worker fight. be prepared to be entertained.
