The East Forsyth safety enjoyed the trip.
"It was my second time visiting, so I was really able to see how much of a family they are up there," said the 6-foot-2, 195-pound Martin. "Everybody at the school, in the town and on the team is very nice.
"My favorite part was spending time on campus and just walking around. It was great having a chance to see everything. Everyone treated me and my family really well."
He spent the majority of the visit with safeties coach Tim Banks and cornerbacks coach Terry Smith.
"It great being around them," Martin said. "They're serious, but also know how to have a good time. They really focused on not making it all about football. They talked to me about the school and life in general."
Martin also had a chance to talk to head coach James Franklin.
"He was busy because they had a camp, but still made time to speak to me, and that meant a lot," Martin said. "I like his personality and he just has a great vibe.
"He asked me about the trip and how I felt about Penn State. He also said he wants me to feel comfortable there and that he was glad I visited."
Martin plans to try to go back for a game this fall
He finished his sophomore campaign with 75 tackles, three interceptions, one of which he returned for a touchdown, four pass breakups and two forced fumbles.
