If you have driven along the entire length of I-35 you will have been on (or immediately adjacent to) 5 D1 Universities' campuses:
- University of Minnesota
- University of North Texas
- Baylor University
- University of Texas at Austin
- University of Texas San Antonio (technicality, it's merely the downtown campus, but counts in my book)
You will also be close-but-no-cigar to 8 more:
- University of Minnesota Duluth
- Iowa State University
- Drake University
- University of Missouri Kansas City
- Wichita State University
- Oklahoma University
- Texas Christian University and/or Southern Methodist University depending on the 35E/W situation
- Texas State University
I'm going to need a ruling here, I've only been on/near most of these campuses while traveling I-35 (from Duluth to San Antonio). My Division 1 foot-stepping number could vary wildly just on I-35 alone between 4 and all 13. I agree with @_33 that this survey wasn't very well thought out.
