Saw Herb Brannon on some of the lists.   Here is a comment Herb that  
I added to another list this morning.   The rest of you on the PRC  
list can read what the Grizzly Bear thinks; you can decided whether  
I'm right or wrong.   Apparently there is some information floating  
around that the accident was caused my malfunctioning computer control.
