Getting ready for Chicago

We're trying to get everything together today for our trip to Chicago tomorrow. The last time that I drove through Chicago I ran into so many big trucks that I couldn't believe my eyes! If you've been to Chicago, then you know what I mean. We're not too worried about navigating the city though because we have a Carmin GPS. We've used it a few times and it works great. If any of you get lost like we do, then a GPS is your answer. You don't even need to look at it as you drive because a voice prompts you when to turn and by street name as well! It takes you right up to the door of the address that you're looking for. Wow, what an improvement in travel.
