I've been a Duke fan since 1977, went to High School, College, and grad school in North Carolina, including one degree from Duke. Does that meet your criteria?
The reactions to my post are interesting. I didn't say anything about Duke being great or anything bad about UNC, State, or UK. I was just noting that when I was in in high school and college, Duke's fanbase was largely from outside NC, but that over the past 40 years, it has become the second most popular program in the state. Seems like a pretty dispassionate analysis.
