So Dinkle is commenting on how he’s only seen the parade while marching backwards as a director. Which is odd for two reasons. I don’t think he’s ever directed the Rose Parade, because if he had I can guarantee we would have heard a ton about it this week. And also, as many people have pointed out, this isn’t Dinkle’s first time in this parade. It might be that Batiuk thought “Marching in the parade for the third time, this time with all those other band directors was an amazing experience, Harriet” was too clunky even for him, but I’m guessing he just forgot.
