Students from UNC usually have the ability to move wherever they like becuase of the quality of the University... I go to Appalachian State and have freinds at Universities across the state.. I notice a lot of younger people move to Charlotte because it is a hot new area and growing fast. It has a good downtown scene and is close to the mountains and near Asheville/Atlanta/and other places. A lot of freinds seem to move to Raleigh. Wilmington is pretty cool and offers a lot to do for a town its size. Anyways, hope that helps.
I myself will probably move somewhere near Raleigh when I graduate.
