There were tickets available all over the stadium this morning on scarletknights.com.
Now it's just the sidelines (10 yardline to 10 yardline) and middle of the upper decks available (everything in the endzone and the corners are gone). Of course, it might just mean that they dumped all those tickets on SeatGeek.
Also, I'm a season ticket holder so I don't look at single game sales often, but the cheapest ticket on scarletknights.com is $85, including fees. That's kinda wild to me. I wish they'd price them so it actually sells out. Who is paying $85 to sit in the upper deck?
