Dan,

   Thanks for seeing what I missed evary time I went though the data. I knew
it had to be some mis-classified observation but after three times through I
thought that I had corrected all the misfits and didn't see that one. New
eyeballs are invaluable after one's looked at data or code a long time.

Very much appreciated,

Rich
