I agree with what you say, and in particular I'd agree that it's common sense, except it doesn't appear all that common, unfortunately(at least from my limited experience, nor your experience from what you wrote).
And in the interest of getting the thread back on track, I wish I could've heard the horn in person on Saturday. From what I understand they were gonna do the old horn last year too, but of course, we got shutout against the Caps that day
