She's quoted in Running Times: "As of now, the goal is definitely to go to college in Portland. I have applied to the University of Portland." http://www.runnersworld.com/elite-runners/mary-cain-going-pro-makes-the-most-sense-for-me?cm_mmc=Facebook-_-RunningTimes-_-Content-Racing-_-MaryCainTurnsPro
Myself, and a few others, predicted this exact scenario over the last several months...that she would, in fact, enroll at Portland and turn pro with Nike. We were pooh poohed by so many that said "No way. She'll go to an Ivy, or Stanford, etc" or "No way. She'll go to Oregon."
Doesn't it seem so obvious now? This was really the only option, and was quite easy to predict in actuality.
