I have a theory that I have kept bottled up for 30 years and probably never would have remembered had this thread not jogged my memory.
1984: I was a baritone player in Spirit of Atlanta. Near the end of our Whitewater finals performance I felt something hang on my foot near the end of our show - when I was in the area of the 35-40 yard line on the (audience’s) right side of the field. Glanced down and saw a piece of rope with a S hook* on it which I was able to kick off my foot and keep going. Leaving the field I momentarily thought “should I tell a judge?” but then it was hurry up and get off the field, etc... Later that night the Garfield incident happens and I thought, yeah I should have told someone.
*Anyone remember the Florida Wave 1984 show? They had a visual section where they lowered horns and let them hang on a rope with a hook…
