Hosted by a former prep rival, Cody Vaz, who played at Stockton St. Mary's, Cooks went into the trip open-minded.
He left convinced he was going to be a Beaver when it was all said and done.
"I didn't want to commit right after the trip, but I knew I was going to end up committing to Oregon State," said Cooks. "I just wanted it to sink in first."
So after spending the week of Thanksgiving thinking it over, Cooks let two Pac-10 coaching staff's know of his decision.
"This weekend, I decided to commit to Oregon State," said Cooks. "I called Coach (Rick) Neuheisel and he said that they didn't want to give up on me but said he understood I have to do what's best for me."
Cooks was the first commit to UCLA in the class of 2010 but over time thought Oregon State might be a better fit.
"They were one of my first offers and they were recruiting me even after I committed," said Cooks. "They compared me to James Rodgers and Sammie Stroughter and want me to do what they did, only better."
Cooks said while he still likes UCLA, he's done for good with recruiting.
"I don't think I'm going to visit," said Cooks. "I'm pretty much 100% to Oregon State and done with it and visits."
Cooks said that he loved his time in Corvallis.
"Everything about the school and the city was good and what I was looking for," said Cooks.
And he'll still get to play in the Pac-10, in the same division as the two Northern California Pac-10 schools nearby. Plus, he'll get to play with a former foe.
"Me and Cody talked about him beating me in high school, but now we'll be playing together," said Cooks.
