For those not from NC, or, who don't live here...
NCSU-Wake used to be a bitter rivalry, until Wake Forest University moved from the town of Wake Forest, to Winston-Salem, in 1956. Wake Forest is a small town in Wake County, of which Raleigh is the county seat (and state capital). Rivalries are driven by proximity and familiarity, and, those two being in the same county made it pretty intense.
WFU moving two hours away to the Triad area, from the Triangle, has hurt them more than many imagined. They're basically an outlier to Carolina, State, and, Duke, now.
Just a little history surrounding Wake-NCSU...when I was growing up, NC observed Easter Monday as its official state Easter holiday, as opposed to Good Friday. And, that was because Wake and State used to play a baseball game on that day, and, the state gave its employees the day off, so they could attend it.
