TULSA, Oklahoma - You'd have thought it was already Halloween day on Tulsa's Brookside Sunday afternoon.

Hundreds of superheroes and princesses and ghosts and monsters lined Peoria Avenue to watch the annual BooHaHa parade.

Children dressed in their Halloween costumes to trick or treat a little early and check out all the cool floats.

Organizers moved the parade to Sunday instead of Saturday this year to help out the Brookside Business Association.
