Whoops, I forgot one more thing on top of the 11 that I already mentioned:
12. Thankfully, the tides are turning against God Bless America and Don't Stop Believing. I spoke with one Dodgers employee who said that he/she had been trying to curtail both of these new traditions, both of which have run their course and are now neither novel nor necessary. For GBA, there is a movement starting to only do it on Sunday games and special holidays (which would make sense); for DSB, I think there is rising sentiment that it's time to move on (after all, there is little believing left to be had here in 2011). Personally, I'm hopeful that this employee gets the requisite endorsements to let these two interstitials fade away.
And take the wave with them.
