I've seen some pretty negative reports from Saturday's game vs. Notre Dame on the /r/VirginiaTech subreddit but didn't see anything on here about it. It seems like it was primarily a student section issue as I had no problems getting in the stadium or to my seat in Section 11. The concession lines seemed to be really long but that was it. I did see some more bottles getting thrown, but it primarily looked like they were from the students as well as a few paper airplanes (again, students).
There was a pretty big scuffle right above us in 9L where I saw some guy diving onto someone else with fist cocked back. Cops came in and took him away, not sure what started that.
I think that students these days aren't used to a packed Lane like those of us from the 00s remember. I'm sure the student section GA doesn't help, but people who have panic/anxiety attacks when around large groups of people probably shouldn't...you know...go to events with large groups of people in close proximity to each other.
