It's actually people tied to folks from the athletic marketing department. They may or may not be alumni.
On a side note I do believe many of the cities could have been better placed but in the end it was up to the person with the box to pick a location. I think it was more about the person with the box and what they wanted to do.
I think Utah (of course) went off well as did Delaware. But I think the Nike campus and the story around what went down to get to it was the best.
Worse IMHO was MN (being from there and seeing the spot, it was horribly placed) and AL (only because I didn't get it).
In the end I hope this is something they do every year and as they do it really develops into a cool promotion. If done right I could see some very big promotion for it.
