Based on what I understand from planning panels in the past, there's a difference between food brought for the event and food that you individually have with you that you share. For instance, Tom always passes around Pocky at the Pocky Club panel. Though for all I know, Pocky Club may be an exception. >> In any case, as long as it's just snack-type food and not cakes or potluck dishes etc, it should be okay. Don't quote me on that, though. ^^
In other news, I got a dowel to make my Prussia flag pole today, and a snazy London Fog trench coat from Goodwill for $7.50! Not that I'll be wearing the coat to Kcon, but when the weather gets colder I definitely will. :3
