Although the vibe is slightly different, I think that someone interested in SMU should at least take a swing by TCU since they’re a 43m drive from one another. Another Texas possibility (besides Rice) is Trinity U in San Antonio.
If you like Georgetown & Boston College, check out another northeastern Jesuit, Fairfield in Connecticut as well as Loyola Chicago in Illinois. If you liked Michigan, then I agree about checking out IU, but also think about Wisconsin-Madison. I know that those 3 have partnered together for various reasons (including study abroad programs).
