Walker, a 5-foot-11, 185-pound cornerback from Charlotte (N.C.) Mallard Creek, was hosted by fellow defensive back Tre Boston.
"I spent time with a lot of [the players], because [Boston and I] went out a lot," Walker said. "I was also with Sean Tapley a lot, because he was with Marquez [North]. I met a lot of the defensive back players.
"[The players] were just telling me how everything went down – classes, school life, how to deal with football."
Speaking of North, he and Walker are teammates and close friends. North is also the top un-committed target on UNC's board.
"I know he's still interested – I know that," Walker said. "I don't know how much. For one, he wouldn't come if he really wasn't still interested. I think he still needs to sit down with his family and decide something."
Regarding North, Walker is taking the middle road. He's talking up UNC, but he's trying not to recruit North too hard.
"I'm putting a lot of things in his ear like the education," Walker said. "But I kind want him to make his own decision about it."
Besides North, Walker was accompanied on the official visit by both of his parents. All of the official visitors were treated to the UNC-Maryland basketball game on Saturday afternoon. Previously, Walker attended the UNC-Duke game in Chapel Hill last season.
"It wasn't all that, because Maryland wasn't good at all," Walker said. "But the atmosphere was good."
Gunter Brewer is recruiting Walker for UNC, but within the coaching staff Walker spent the most time with Dan Disch, UNC's defensive backs coach.
"[Disch and I] talk here and there over the phone, but we've hardly got to talk in-person," Walker said. "I got to know him a little better [over the weekend].
"He was just telling me to be ready. At one point, he went over some of the defenses."
Walker closed out his stay with a one-on-one meeting with Larry Fedora.
"He told me he admired my loyalty for not going to other schools," Walker said.
Walker and Fedora are still in the process of scheduling Fedora's in-home visit. Brewer will be at Walker's home on Thursday and there's a chance he could have Fedora with him.
