Got my tickets today. Due to the Boston Bombing, I think, the rules have tightened up a bit. I would read the rules on the official website carefully.
Normally, one does not know how tightly the rules are followed by the staff till one gets to an event, but in light of the bombing, I think we might assume
that they could indeed be followed closely. It is a pain to get to an event that is far away from one's hotel only to be told to loose the big oversized bag/"purse".
Camera policy is the standard "6 in/ 200 mm lens" one.
