I think what corinowalk meant was I shouldn't go to somebody who is dead set on winning the money and points.
And thanks stillstandin! It does make sense, I think my worst worry is not being able to find the right cow, or pulling the wrong one, or letting the wrong cow out.
When you are at the line before flag is up - start scanning for numbers. That way when they call Flags up - you have a direction to head to instead of getting in the herd and frantically scanning.
What type of sorting is it?
