Abomb bought some of these little megaphones for less than a buck each, red and no stickers. They are LOUD! I for the life of me don't know why the Cards don't give them out to the crowds (say, game one vs. SF) to help fans get even louder.
We have been asked just once on bringing them in whether we could. The security lady said "the guidelines say no noisemakers" to which my wife replied "this doesn't make any noise, my voice does. It just amplifies it." She went through. About 8 of us have these in our section, and as the guys in front of me can attest, they are freaking LOUD!!!
Run, don't walk, and get these things ASAP for Monday Night. There will be a ton of Bears fans there so we need all the help we can get. LOUD is where it is at. Let's rattle Grossman like he's never seen....let the Frat House ROCK!
(and it is just a coincidence the pic I found had Cardinals on it, I didn't even try.)
