We Americans are so easily duped. The price for regular unleaded at my local gas station has dropped from $2.029 to $1.929 over the last two weeks, and I found myself thinking, "what a bargain!" On the other hand, I did three business trips to Europe this year. When I visited Edinburgh, a city I dearly loved, I noticed that gas was priced at 89p per litre. After a little number crunching, I realized that was just over $6 per gallon. I didn't get much sympathy from my hosts when I whined about paying $2 per gallon.
