 August 3rd or September 7th. Those are all Saturdays, and they're all mega blast Saturdays out at First Energy Stadium. And the Lehigh Valley Zoo tickets can be used on any normal day up at the zoo. Sometimes they have special events. Just check the schedule to make sure you're not going up there on a special event. Otherwise, you will have to upgrade your ticket. This is a general admission ticket for a regular zoo day, but you can go up there and see the new red pandas. I've seen pictures online. They look adorable, Bob McCool.
