John Ball Zoo is getting in on the Holiday spirit with a Halloween themed weekend John Ball Zoo Goes Boo. Each of the next two weekends, October 16-18 and October 23-25. From 10am to 3pm, the Zoo will be open and ready for the patrons to flow in for trick-or-treating, activities, and the animals (obviously)! Costumes are not only allowed, but they’re encouraged. Price is $8 for non-members and $3 for members. Children under 2 are free of admission. Put your best costume on and make a weekend visit to John Ball Zoo.
