Some folks are reeling after yesterday's brush with significant arbitrariness (if there is such a thing) as oil prices briefly hit $100 a barrel in trading before settling slightly lower. The significance of $100-a-barrel oil has often been debated, with environmentalists and others coming down on all sides of the issue. Some greens get all freaky. Some rejoice since it could lower consumption. Others think it's no big deal. But there it is ... $100. Now, if you'll excuse us, the odometer on our office stationary bike is about to hit 11,111 miles and we've got a party to plan!
