Ahhh...so that's what a land grant college is. That term has been thrown around allot, and I thought it had something to do with prestiege. It just refers to a different mission than a "non-land grant" college.
Now the term "flagship university" sounds to me like a more subjective term. As an outsider looking at the Dakotas, I would think that UND, USD, SDSU, and NDSU are all "flagship" universities...I guess it all depends where you have your allegiance.
