Among them is a float by the AIDS Healthcare Foundation honoring the 49 victims of the Orlando Pulse nightclub shooting.
"The AIDS Healthcare Foundation has put together a really heartwarming float this year honoring the Pulse nightclub victims," said Stefan Pollock, spokesman for Fiesta Parade Floats. "One star for each of the 49 victims. Throughout the parade, 49 doves will be released during the parade route."
