I intend to visit Iowa City in August and stay there for 3 weeks. In this period, I will drive to Chicago for a 5-day visit and have plans of visiting other places in central or eastern Iowa. Considering this, I would like to see if you can help me.
A) Which is the best way to drive from IC to Chicago? I read that I-88 has toll points. Is it easy to pay for them in cash? (once rental cars companies charges a lot for their toll-free equipments, specially for a 3-week rental).
B) For a weekend, I am considering visiting Dubuque or Davenport, because I would like to know a city that is bordered by Mississipi river. Which of them you would consider better for a 1-day round-trip with family?
C) At Iowa City, I would like to watch a Hawkeyes football game at Kinnick Stadium. I see that a single ticket $50-up in their official website. Is it the real price or I could get it cheaper if I buy it in person?
Thanks for all your help in advance!
