We will be in NYC in a couple of weeks for our 3rd trip. I can navigate the subway pretty well and feel comfortable with it, but I always have trouble finding which direction I need to go once I emerge from the subway, especially in a new area or one that has more than one entrance/exit point. On our last trip we walked 1-2 blocks the wrong direction to get to Katz's Deli when I should have just walked straight. I understand the numbered streets are east/west and numbered avenues are north/south. Is there any trick to this or am I just directionally challenged?
