Quick Question

So I'm planning to cosplay as Fuka Kazamatsuri for the next couple of convos. I'll be needing a baseball bat for the costume to be true to character, do you guys know if those are allowed at convos?

I think anything can be considered a weapon I don't think it's allowed. I've found this thread maybe it can help you http://board.otakon.com/index.php?showtopic=22499
