      Limbo has been plutoed. No half way house any more. It's heaven or hell.

      Winter is dead. The break the university community has just returned from is ostensibly known as winter break. But those who stayed in the Iowa City area know the sad truth: The four seasons Midwesterners grew up with have been Plutoed.
