Anyone else going to the Brooklyn Book Festival?

Thought it might be fun to swing by and check out... going to take my SO along too. There are so many interesting sounding panels, it's hard to choose my schedule!

Etiquette question: Since there are going to be lots of industry people there (mostly as vendors from presses and literary magazines), would it be prudent/allowed to slip them a business card in case I submit something to them later? I imagine they're so busy that a card will probably just get lost in the shuffle, but on the other hand, it never hurts to try, right? Of course I'm afraid that this will be seen as terribly rude and pushy! Thoughts?
