"I had a basketball game Friday night so I wasn't able to get there until early Saturday morning," said the Eagle High School athlete. "Coach Kelly Bills picked me up at the airport and brought me down to Provo."
That Saturday morning, Mangum and the rest of the recruits met for breakfast, where they listened to President Samuelson speak.
"Saturday morning we had a breakfast with the rest of the recruits and Coach Mendenhall and some of the academic professors," he said. "Then we toured around some of the Student Athletic Building and had some meetings there."
After lunch, the recruits got to participate in a group activity.
"We went to the Provo Beach Resort where they have this indoor surfing thing," Mangum said. "It was a lot of fun. I didn't do it because I was still kind of sore from my basketball game from the other night. I had hurt my calf and was still in a little bit of pain, but I wish I could have done that though.
"All the coaches were there watching and that was a lot of fun watching all the other guys trying to surf. I was there laughing and watching those guys. It was a lot of fun."
Apparently, the best surfer of the group was wide receiver recruit Dylan Collie.
"Yeah, I would have to say Dylan was the best one there," Mangum said. "His first try he got up and did well and was a natural at it. He's athletic so it doesn't surprise me that he was able to get up. Overall they're a pretty athletic group so it was fun to watch those guys, but Dylan was the one that probably did the best out of the group."
After riding some waves, the recruits headed out to watch some basketball.
"After that we all went out and watched BYU play Santa Clara and that was a lot of fun," Mangum said. "I hadn't been to a BYU basketball game in a while and it was a lot of fun for me to see it live. The most fun for me that day was probably the basketball game.
"That was probably my highlight of the day. It was a lot of fun being in that environment and getting a taste of what it's like there. Like I said, it was a lot of fun."
Meanwhile, Mangum had nothing but great things to say about his host for the trip.
"Riley Nelson was my host for the trip and he's an awesome guy," Mangum said. "He was a lot of fun to hang out and is a funny guy. He's really cool and he was lot of fun to hang out with. I was actually pretty glad that he was my host because he was a lot of fun to hang out with."
Mangum got a chance to pick the brain of his quarterback host.
"Yeah, I spoke to him a little bit about what it's like being a BYU quarterback, and he gave me a lot of great information of what's expected. He helped me to better understand what to expect and it was great being able to hear it from him. I'm actually pretty excited to be a part of that BYU fraternity. Overall I had a blast out there for the day being with all the guys."
