Did a little research and all I could find was that the Donald Duck birthday parade ran sometime in 84. However, I can tell by your photos that it is not the parade you have pictures of. I also know that it's not the Tenncenial Parade. I remember that parade had Mickey and Minnie riding on a float with a big "10" on it. I'm not sure this parade had a name other than maybe the Main Street Parade. Wasn't for a big celebration or anything so there doesn't seem to be too much info about it anywhere.
