For me, Day 2 of New York Comic Con 2013 was better. I actually got to visit the main floor instead of waiting in autograph lines. I bought a ton of Doctor Who stuff plus t-shirts that proclaim my love for Doctor Who and Big Bang Theory. Saw a red Darth Vader break dancing but only got pictures of his friend.
There were some great costumes that people put a lot of thought and hard work in to. I may even dress up next year but only for one day. Some people wore their costumes everyday and by the last day they did not smell so fresh.
