Students at River Valley School in Lemont kicked off their Halloween celebrations with a costume parade around the school's campus Monday morning.

Popular costumes included characters from the game "Angry Birds," cartoon characters, witches, athletes and bumble bees. Creative costumes included a Crayola crayon, a vending machine and the Michelin Man.
