Willow, sorry for laughing, but I find it funny all the talk of benzene when cars are most certainly the major source for this pollutant. I know this harkens back like 8 or 9 pages to the "stop driving" points, but benzene was ceretainly the wrong nit to pick. It did give Thorfinn a great math workout, however.
