Smart girl. My daughter looked at UT too, but decided on a small private university in Georgetown a few miles north of Austin. She loves it and heads down I-35 a few times a week to visit her high school friends who go to UT. The only thing I hear her UT friends complain about is the campus parking situation. A few of them left their cars at home because it's so bad. They say the campus shuttle works well.
My next in line would NEVER want to go to a large university and will wind up at a small scholl as did your daughter, but my oldest always wanted a big school. And I wanted her to go to a midwestern or southern university in order to get a different perspective on life (we live in NJ).
