Amber sighed as she came up short.  She counted, then recounted, and counted again.  Finally, she had to admit that she was missing two cows.  She walked back over to King.  "All right, come on buddy," she said.  "We've got to go look for those two."  She mounted up again, and guided him out across the fields, trying to find some likely spots for a pair of cows to be hanging out.
