Earlier in the day, the Cubs staff stopped at the 2nd Battalion, 24th Marines to serve lunch to about 250 military service personnel.
The caravan tour is a lead-in to the Cubs Convention, which opens Friday at the Sheraton Chicago Hotel and Towers. This will be Renteria's first convention.
"They've said it'll be something I've never experienced before in my life, and from a few conversations I've had with different people, it seems that will be the case," said Renteria, who will answer fans' questions in a Saturday afternoon session. "It is evident that the city of Chicago loves their Cubs and they want the Cubs to have success and we feel the same way."
The winter fan fest also is the first chance for some of the Cubs to meet their new manager. Jackson is coming off a season in which he led the Major Leagues in losses with 18. It wasn't how the right-hander wanted to start the first year of his four-year, $52 million deal with the Cubs. Renteria's message to Jackson? Learn from what happened and move forward.
"That's the only way we'll move the club in the direction we'd like it to go," Renteria said.
Jackson, who welcomed a new daughter in the offseason, was eager to take Renteria's advice.
"As an athlete, when you have a season like I had last year, if anything, it makes you more eager to start the next season up," Jackson said. "That edge comes a little quicker, and you're more ready and more excited to go out and perform the way you know you can perform."
What about Renteria?
"He seems like he's ready to go," Jackson said of his new skipper. "He's excited about being a manager of the team. He definitely sees the potential the team has and he understands what we're capable of doing."
Jackson said he had no clue Dale Sveum would be dismissed after the 2013 season ended. Maybe change is good?
"I hope so -- I've changed a lot of teams," said Jackson, who is playing for his eighth team. "I hope change can be good. Change doesn't hurt. We have a great team, we have a great manager who is eager to get out and be with the team and help the team learn and teach us different things. We're ready to go."
