 The Little Rock Zoo has once again partnered up with Highland Dairy to offer a day of deep discounts on zoo admission. The Highland Dairy Dollar Day is coming up this Saturday. It means anyone can visit the zoo for less than the cost of a bottle of soda. The zoo will also sell Highland products for a buck, including iced tea, milk, and other beverages. 2024 marks the 15th year for the popular discounted day of admission.
