Penn State rolled past the Hawkeyes, 38-14, in front of a sold-out Kinnick Stadium. The game was played in primetime.
"I thought it was definitely a good opportunity to see both offenses in person," the 6-foot-4, 195-pound Thorson said. "(The Nittany Lions) played a great game. Their offense was pretty much clicking on all cylinders."
The Wheaton (IL) North signal caller appreciated the game's atmosphere after last time visiting Iowa City for a day game.
"It was nice to get back there and see Iowa's facilities and their football stadium again," he said. "It was cool to see a night game at Kinnick. It was pretty awesome.
"They have a great fan base there. It was a packed house and they were into it."
Thorson met with his lead recruiter, Iowa assistant Lester Erb.
"We just discussed my previous games and we talked about their game," he said.
"It's an exciting process," Thorson said. "I'd probably like to decide before next football season to get it out of the way. I don't have (other visits) planned right now. After the season, I'd like to go visit some other places.
"I would definitely want to see the schools that have offered me. I'd like to see them again. Other than that, I'm not really sure right now."
Wheaton North runs a spread offense, but Thorson said he'd be comfortable in most schemes.
"We have a lot of quarterback runs and also throw a lot," Thorson said. "I didn't really picture myself in either offense (Saturday night). I was just watching both offenses to see what they did."
Thorson and his North teammates head into the Illinois postseason this week. He's likely to slow down recruiting during that time.
"I want to focus on the playoffs," he said. "I'll worry about the other stuff after the season. I think out chances are high. We have a great group of players this year. We have a tremendous defense. Our offense has really come together."
