I was at the 2016 game as well as last night's game. For both games, the stadium was unbelievably loud. Aside from the visitor's section and a few patches of Scarlet & Gray, there was white everywhere. The pumped-in noise and video scoreboard kept the home team's enthusiasm up with videos of PSU victories over OSU (lots of clips from 2016).
In 2016, we were able to go for most of the day and tailgate with friends of the better half. Everyone was very friendly and what was striking was the lack of faith (for the most part) they had in PSU. Comments such as "I hope it's still a game by halftime." Obviously, the after-game enthusiasm was huge.
This year, the confidence was definitely higher. Our tickets for both 2016 and 2018 were from season ticket holders in the alumni section with older families and the comments were VERY different this year. Even to the point of the gentleman behind me stating that Michigan isn't OSU's rival anymore...it's PSU. In 2016, they hoped not to be embarrassed off the field. This year, they expected to win.
The crowd and atmosphere was electric and their fans were in the game the whole time. I can't imagine how loud and intimidating it must be to be on the field with a sea of white and white pom-pom's everywhere. Their student section is huge and on the drives that started there (the 96-yard drive at the end of the game started in the student section), it had to be next-to-impossible to hear anything.
For the most part, everyone was very friendly (again, I was sitting with an older crowd) and didn't say anything too vile about the team and players. At the end, it was very quiet walking out of the stadium. Stunned disbelief sums up what I saw. EVERYONE couldn't believe they took the ball out of McSorley's hands on the 4th and 5 play (I couldn't either). And calling those time outs hurt once they turned the ball over.
Overall, it was a great experience and this year's outcome made the trip that much better.
