"As we gasped and laughed at the difference between our borrowed joyride and our real-life cars (as the owner of a base-model 2000 VW Passat, I have the most fly car of the bunch), we were well aware of several layers of irony. Down in the valley motorists were waiting in long lines for scarce gasoline at the stations that were open at all, due to the supply crunch in the Southeast following Hurricane Ike. We, meanwhile, were burning gas like it was going out of style (which, come to think of it, it soon may). Then there was the improbable identity of the four merry riders: all of us activists in the growing environmental movement within evangelical Christianity, concerned not least with the reality of and remedies for human-induced climate change. That climate change is caused in part, of course, by the carbon dioxide that we were gleefully generating every time the Beemer let out a particularly gratifying growl. Let's just say there was a hint of guilt in the pleasure."
