The tweet is from last night. The tickets are about to go on sale. After 8 AM, you can use that link to buy online, and I'd do it ASAP if you want good seats for Homecoming or Parents Weekend. I'm looking at you, freshmen Baylor Line members that will forget and then freak out at the last minute when your parents want to come. Yeah, you.
Don't be the guy that has to StubHub tickets for your parents or stand in line at FCS right before the game starts. I've been that guy. It sucks.
