DAY #2 Leaving Chicago. STICKER SHOCK?

"All is relative." Who would-a-thunk that we'd be happy with $4.09 for
gas??? But in Naperville, IL it was $4.22. So when we had to get off for
gas, we were happy to find $4.09. Yup. All is relative. We're going to
cross the Mississippi soon, heading to Dubuque, Iowa; then north into
Minnesota. P.S. 50 miles down the road in Clinton, Iowa, just across the
Big Muddy, where we had lunch along the shores, gas was $3.75. Go figure.
