I drive about 25,000 miles a year, so changes in gas prices are something I notice. I spend about $13/day just for the round trip commute to work, assuming I don't also drive myself to a story.
Today I'm saving myself some money by reporting from home via Skype on my iPad. Technology trumps my carbon footprint! The downside: bad lighting. I don't look so hot. Holding an iPad at arm's length is not the most attractive angle. But I saved enough to buy lunch!
