When Josh, E.L., Rubin, and Kyle first reach Austin, there are a few clips of the city before they arrive at Tiffany's dorm. In the first clip, they are exiting the interstate and there is a sign that says "University of Texas . . .", although throughout the movie, Tiffany is said to be attending the "University of Austin" (obviously they made up this university--that's not the point). "Texas" could have easily been edited over as "Austin".
