I was in the bicentennial Disney parade at Disney World (when it was still truly Disney). My sister SHOULD have been there as she was the star lead majorette, but she quit just before this. She was in a lot of local parades (I was just little, and did not do much), mostly summer.
As it was, people were passing out for the Disney parade. I remember mostly just being in a holding shelter until our time was up, and hearing about the teen girls dropping from the heat.
Yep, I did three Disney World parades, and someone passed out each time. One was a girl who insisted on wearing blue jeans under her uniform. Dumbass. Happened to be my girlfriend at the time. 8~)
