In the Old Garden, during the playoffs, additional noise was generated by banging on the electrical panels around the perimeter of the Garden (which made a sound like thunder). For years, I've been wondering what could be used to replace that in the new Garden. I finally heard it during Game 5 of the Conference Finals. Somebody figured out that the retaining wall around the very top seats of the Garden (way up, above the balcony) really reverberates when you whack it with your hands. Some guys (maybe 5 or 6 of them) in the corner were doing it during Detroit free throws in the fourth quarter, and it really took the volume up a notch. We need the entire level 9 crew doing that during key moments of the Finals. If I can hear myself screaming, we aren't loud enough.
