I have this issue with umpires in my area. I always ask them before the game how they call it so I can let my players know that is how it will be called. If they say the runner must continue to 2nd or they are out, I will point out that the look back rule is in effect and they are allowed one stop and ask them to look it up. They won't change their mind for that game but I want them to look into it in the event they ump another game we are in. I have asked the state ASA chapter to go over it with their umpires but it doesn't appear they have done anything about it.
