Nardo, a 6-foot-2 235-pound defensive end from Lancaster (Pa.) Catholic, attended the Tar Heels' July individual rising senior camp.
"It went good," said Nardo. "It's a very nice campus and the coaches are very good coaches and they want to win."
While in Chapel Hill, Nardo worked with both defensive tackle coach Kenny Browning and defensive end coach Danny Pearman.
"They are very good coaches and they know what they are talking about," said Nardo. "They said they liked my technique and my hand work."
Nardo has also attended camps at Iowa, Northwestern, Connecticut, Virginia, and Boston College.
Despite the in-depth exposure to several schools during the summer camping circuit, the lack of any Division I-A scholarship offers make it difficult to name any favorites.
"I really don't have any favorites," said Nardo. "Of all the schools, I like things about all the schools [I've camped at], but none have really stuck out that much yet that I could name a top three or top five."
Although Nardo would like to put his college decision behind him sooner rather than later, most schools are awaiting senior season results.
"A lot schools have said they want to see senior film [before offering]," said Nardo.
For Lancaster Catholic, Nardo plays defensive tackle in a 3-5 scheme on defense and guard on offense. During his junior season he collected 82 tackles including nine for a loss and four sacks. Nardo received second team all-state and first team all-conference honors.
