"It's a rivalry game and it's after my season," Harrison said.
Harrison plans to begin the drive to Chapel Hill the day before and stay in the area until Sunday. FSUS plays its final regular season game on Nov. 8. If a deep playoff run forces Harrison to play that Friday before the Duke game, he says he'll depart immediately afterwards.
Accompanying Harrison on the trek will be his brother, but his mother will join them if she's able to work out her schedule.
In mid-July, Harrison spent a weekend in Chapel Hill just before verbally committing to Larry Fedora.
"I just want to see what the overall game day experience is like," Harrison said. "I want to see what the fan base is like [and] how the guys come out and play. I'm trying to see the locker rooms. I'm trying to see how the coaches react to the environment. [I] just want to get a feel for the game day experience."
During his visit in mid-July, Harrison was introduced to fellow Floridians Tre Boston and Jabari Price. Harrison has maintained contact with both since his visit.
"I'm just talking to them about the season and trying to keep them spirited, because they're not doing too hot right now," Harrison said. "We're 1-4 right now. I'm just talking to them to see what's going on and what they're thinking and encouraging them."
UNC's lack of success has also affected Harrison to a degree.
"Sometimes my mind drifts on whether I made the right decision or not," Harrison said. "But I know at the end of the day it's right for me, because the football and athletics there are great – and they're going to be better in a couple of years. We're real young right now [and] we're playing with walk-ons. I know that we will be good, because we have great players coming in. We'll be a team to watch. "
Constant communication with UNC's coaching staff has eased any of Harrison's concerns. He says that he speaks to someone from UNC twice a week.
"I talk to Coach [Dan] Disch, Coach [Gunter] Brewer, and Coach Fedora," Harrison said. "Our conversations now are more about the program and what they're doing and what kind of things they're trying to get setup for me when I get up there."
Harrison did make a visit to South Florida about a month ago. He says he made the visit as a guest of his teammate's.
"No, no, no, they don't need to worry about anything," Harrison said of the UNC staff. "I'm 100-percent [committed]."
Regardless, Harrison says he may not be finished visiting other schools. He's considering spring and summer visits to Kentucky, Louisville, Tennessee, and Vanderbilt.
Harrison says after he initially committed interest from other schools spiked, but it has declined since then.
"When I first committed, a lot of rivalry teams started to hit me up and offer me, like NC State," Harrison said. "But now, it's starting to die down a little bit. Everybody has started to run away from me, because they know I'm 100-percent committed."
The UNC coaching staff hasn't singled out one position for Harrison.
"Coach [Disch] said I could play anywhere in the 4-2-5 defense," Harrison said. "I could play walk-down safety. I could play free safety. I could play corner. It's all about where I feel most comfortable when I get there."
Harrison stars at quarterback for FSUS, but he does play situationally at defensive back. After starting the season with two losses, FSUS has reeled off four straight wins. On the season, Harrison has thrown for over 800 yards, rushed for over 300 yards, and ten total touchdowns.
