Four Dollars a Gallon

I was driving in Chicago last weekend and I noticed that gas prices have finally hit the four dollar mark. They're a little bit cheaper here in the 'burbs but I expect prices here will reach four dollars soon enough. Between Kelly and I, we barely drive 100 miles per week so, unlike everyone else who has to drive far every day, we are not as affected by ever increasing prices. Let's hear it for public transit! But I can imagine the pain of those who do drive a lot. At some price point the current lifestyle model of driving everywhere becomes unaffordable to all but the wealthy. Our region has better public transit than most parts of the country, but it is still far from ideal.
