The kids got to put on their Halloween costumes early when we attended Zoo Boo last weekend. We had two Optimus Primes, a Spanish Princess and Dorothy from the Wizard of Oz. It was cold, but the kids didn't complain. I'm guessing the free candy could have had something to do with it. It was our first time trick-or-treating at the zoo. I can definitely see this becoming an annual tradition. We had a lot of fun.
