I had a pretty good time near the end of the day (I only went Saturday), when I actually started getting comics signed. Picked up a sketch cover by Asia Ladowska, and got a commission for my son's room from Rachelle Rosenberg. All-in-all for my third year it wasn't bad, but I definitely had a better time last year when it felt less crowded.
Spent the better part of the day trying to get in celebrity lines for the first time, and ran into so many problems that I gave up on "meeting" most of them. I think I'll stick to smaller cons on meeting non-comic people.
