Defining an Imagine Cup region

In case you read the Regional results below and wondered how Boston U
could end up in the Northwest Region, or University of Hawaii Manoa in
the Mid-Atlantic reason, here's the answer: The names are just a fun
way to break up the competition into smaller chunks, and aren't
geographically relevant to the locations of the schools in them.
Basically, it was more interesting to put "Midwest Region" on a 1st
Place trophy than, say, "Region 4". :)
