What can I do on the long car ride to Chicago?

We are going to Chicago in 7 days [yay!] ang we have to sit in the car for about 6 hours instead of taking the train, [yuck!] So we are going to be bored the whole time!! [ahh!] We are going with the pastor from my church [well she's driving my group] and she's wild! [hah!] We are going to be playing the finger game, making bracelets out of string, drawing, talking and reading. [maybe] some eye spy and the letter game, but any ideas? Games to play or songs to sing?
