I think I may have a solution for Glendale's parade theme problem.
It would require very little change to the design, make most people happy and also add a bit of humor to the “Just Imagine” theme.
Just imagine an elephant pulling not a circus wagon, but an old fashion paddy wagon. Its load would contain circus-animal trainers and poachers looking out from behind the barred windows as they were hauled off to jail.
Just an idea. And don't forget to add a slight smile to the elephant’s face.
