Chevrolet is again hosting customer Appreciation Days at Hershey Park in PA for Chevy owners this year. You can request up to 4 free passes per household (retail value of $56.95/ticket!) to be used on July 7th, July 28th, and August 25th. This offer in the past has been limited to PA and surrounding states (NY, WV, VA, DC, NJ, DE, MD) residents. You will be required to enter a unique registration code that you have received in the mail, so have it ready. Yay for free family fun!
