This final note on the way out. There was a brief rip in the economic space time continuum today. Don't know if you felt it.
Long about mid-day, Apple shares picked up enough ground to make it the most valuable publicly traded company in the country -- worth $343 billion. It bumped Exxon out of the top spot.
By the close, though, order had been restored, Exxon was back on top. But one never does know what tomorrow will bring.
