My husband, baby and I came to the zoo today from Iowa. After we waited in line to buy our tickets for 15 mins. We finally got to the window to buy our tickets. After we bought them the lady at the gate told us the zoo is closing early today..... We asked why and she said so they can have time to put up zoo lights. An hour and half is not enough time to go through the zoo. Why are they putting up lights on the busiest day of the week? Why didn't they update their website?
