The UNC alumni association just released this presentation on Tar Heel Pride: http://alumni.unc.edu/membership/pride/
I watched it half a dozen times and then kept playing it on repeat in the background so I could hear the Alma Mater while working.
This has done a better job of explaining what being a Tar Heel means than I have yet been able to do.
I do believe when I go home in a few weeks, I will need to swing by Chapel Hill. (Hint hint, parents.)
