Believe what you want. I don't care. I don't believe you went to Duke or know anybody that did, or really even have a wife that went to UNC that willingly married you. But I do pull for the baseball team( which didn't go to the NCAA tourney for the first time in over a decade), wrestling, soccer etc etc.. I've seen games in different sports from Boshamer, the Dean Dome, Kenan, Carmichael, to Fetzer Field.
I don't feel the need to let people know where I went to school. But let's just say that I come from a Carolina/Duke alumni family. And I pull for more than just the basketball team, unlike you and your school that you went to that you only pull for in basketball.
