in case you missed the comment, here is some inside info from marc:
"I got some inside information about the girl with the duck from a friend of mine who was talking to her.
Security wasnt going to let her in because they said there were no pets allowed, to which she said "this isnt my pet, its my friend". When that didnt work, she said something along the lines of "I see other birds flying around in there, and they arent being kicked out" and then (my personal fav) "ok I will leave him here and he will fly in and meet me later".
I guess one of those things worked, because there she was outside Panic walking a duck with a leash. She only made it about 10 feet in an hour because everyone kept stopping her to take pictures, and all the little kids were petting the duck."
