Rule Books at the Diamond

[Michael Hughes]

Two schools of thought for the following question. I'd like to get some other opinions.

As an umpire, should you have a copy of the rule book with your at the diamond? I have heard reasons for both having one and consciously not bringing one to the diamond.

I subscribe to the theory that it is better to stop a game for 10 minutes, consult the book and make sure of a call on the field, than it is to not have the credibility of the umpire undermined at the time and have the game protested on the basi of a bad call.

Thoughts?
