We took our son to a spring game before he was 4 and he had a good time and last the entire game. So we then took him to the PSU-Michigan game in 1994 in Ann Arbor. He did great, lasted the entire game. Was chanting defense, defense in the 4th quarter and after the win was chanting we're number one along with all the other Psu fans.
Only bad thing that happened was he needed to pee during the third quarter and we were about row 10. So I threw him over my shoulder and ran up 70 rows, hit the port-a-potty and headed back down. Of course he was laughing the entire time.
He is now a PSU grad and a trauma and critical care surgeon. Though he did go to med school at OSU.
