But Spencer had never been on the UCLA campus, only a game at the Rose Bowl, prior to this weekend's official visit.
The trip to Westwood, though, confirmed to Spencer that he was making the right decision with the Bruins.
"I loved it there, it was amazing," said Spencer. "I know I made the right choice in committing there and this weekend confirmed that. I can't wait to get there."
"Yeah, there was a lot of recruiting going on with those guys," said Spencer. "I feel pretty confident they'll end up at UCLA."
Spencer will enter UCLA as a cornerback, and said that head coach Jim Mora and defensive backs coach Demetrice Martin were trying to keep receivers coach Eric Yarber away from him.
"Coach Meat and Coach Mora were trying to keep him away from me and distracting me cause he wants me as a receiver," said Spencer. "I'll start off at corner, though, but they'll throw me in some offensive packages."
Spencer said the UCLA campus was eye-opening.
"It was obviously my first time there but the campus was just beautiful and amazing," said Spencer. "I was expecting it to be beautiful, but it was a really beautiful campus."
The visitors also got to visit the Rose Bowl.
"Going there on Saturday, when it was empty, it looks amazing," said Spencer.
Spencer said the highlight of his trip was talking with Mora.
"My highlight was just having a one-on-one conversation with Coach Mora, talking about everything, from the depth chart to how school and how practice works," said Spencer. "It was just great sitting down and talking to him."
Spencer said he also got to see some designs of the new football facility.
"They showed us what the new facility is going to look like, the new weight rooms and then the construction on the new turf fields," said Spencer.
This week, Spencer will welcome Mora and Martin in to his home.
"Coach Mora and Coach Meat are coming to my house on Thursday," said Spencer.
Spencer said he won't be visiting anyone else.
"I'm 100% solid to UCLA," said Spencer. "I'm going to talk with Coach Meat about maybe coming back up and visiting unofficially when they have visitors the next weekends."
