Bergen said the Cyclones certainly didn't hurt their chances with him, and could make his decision that much more difficult to make.
"It was a great visit," said Bergen. "I got to meet all of the coaches and the coaching staff was awesome. They had gotten a lot of snow and it was nice and cold, so I enjoyed that. They showed me all of the facilities and they were awesome. The Engineering program is ranked higher than South Carolina and Pittsburgh.
"We went to Hickory Park for lunch and that was some good barbeque. I hung out with a lot of the players. My host was Ben Barkema. It was a really great experience for me."
A decision may come as soon as this week, says Bergen.
"I'm thinking it through," he said. "I really did like Iowa State a lot. Talking to all of the coaches was great, and I'm going to be back in touch with them. Hopefully I'll be making a decision within the next couple of days. I don't really have a favorite and it's really up in the air right now. I've got to sit down and think about what I really want to get out of my college.
"I am scheduled for Illinois this weekend, and I'm probably going to take that too. I could cancel it depending on what decision I make."
ISU also hosted Fort Lauderdale (Fla.) Stranahan cornerback Daniel Dufrene on a visit this weekend. The former Minnesota commit opened up his recruitment late last year, and has since taken visits to Vanderbilt and ISU.
"It was like a little college town and I liked the atmosphere," said Dufrene. "I got to see some of the indoor facility and the new locker room. I got to see the stadium, weight room, and whole campus.
"Compared to Minnesota, it was a little smaller. Minnesota was so big that I couldn't really get to see the whole campus. Vanderbilt was too small. Iowa State was just right in the middle, not too big and not too small."
Although Dufrene said he would like to make a decision shortly, he added that another visit could be on tap for this weekend.
"I haven't made a decision yet," he said. "It will probably be a few more days. I don't really have a favorite right now; I'm still thinking about it. I have another visit this weekend to Florida State."
