On Saturday evening we went to the Zoo's Halloween celebration. The kids get to dress up in costumes and "trick-or-treat" around the zoo after hours. Most of the animal exhibits are closed, but there are a few animals who come out in the early evening hours and are much better to see than during the day. It was very crowded, but the crowd moved well enough and we had a great time. Nathan was Bob the Builder and we took Nathan's friend Ellie who was a Bee. They were super cute.
