Students leave behind state financial aid, incur added transportation costs and pay ever-higher out-of-state rates set by underfunded universities. Why do they go?

Some yearn for independence or fun (ski Colorado! Vermont!) or are lured by merit aid (the University of Alabama, Ohio State, University of South Carolina). They may have been shut out of their own flagships (California, Texas, Illinois) or are taking advantage of reciprocity agreements (Midwest Student Exchange Program), which allow neighbors to pay reduced or in-state tuition.
