Longhorn fans...and law enforcement officers.
And...more law enforcement officers.
"It doesn't start at the gate. I think sometimes people think it starts at the gate. For us it starts at the edge of campus," said UT Police Chief David Carter.
This week the State Department issued a Worldwide Travel Alert urging U.S. citizens to avoid large crowds and be careful at holiday festivities.
"At the current time, there are no specific threats to this game or the University of Texas. But as we all know, the way things are across the nation, we have to be prepared and be able to respond to those things that we may not be aware of," Carter said.
As tailgaters like Blake Fincher have Thanksgiving dinner before the big game against Texas Tech, he says the stepped up security at Darrell K. Royal stadium doesn't bother him.
"Sure you've seen a little bit more of it and there's been some perimeters established but it's nothing that's intrusive or invasive," Fincher said.
UT Police Chief David Carter says the campus police force is on "tactical alert status." They've been that way even before the terror attacks in Paris.
"The vast majority of the time we have to operate as individual officers working individually with a citizen or a student or visitor or faculty. To where we can actually come together quickly to respond as a team or as a small unit," Carter said.
Carter says there's more than 200 officers on hand from multiple agencies both uniformed and plain clothes.
"I think it's great that everybody's being vigilant and upping security. But at the same time I don't feel any real threat I mean I'm going to pay attention to my surroundings like everybody should," Fincher said.
Tailgater Benny Torres feels the same.
"We don't feel fearful and we've had a great time actually so I think they're doing their job and I think it's going to be a great night," Torres said.
Both Torres and Fincher don't want the bad guys to ruin the day.
"We're having a good time. We're not going to let terrorist threats deter us from having fun and enjoying ourselves but they're doing their job it's pretty cool," Torres said.
"That's exactly what they want is for us to be scared and not go and do our pastimes but that's crazy," Fincher said.
You've heard "if you see something, say something."
Chief Carter told FOX 7 yesterday, there's a phone number that will be posted in various spots in the stadium during the game.
It's a number you can actually text to so if anyone sees anything suspicious they can let authorities know.
