Once the lineup cards are submitted (approx. 5 minutes before game time), the umpires take control of the field and the crew chief becomes the person who decides whether to delay or postpone a game (and if/when to restart).
A firewood moisture meter can be used to determine the moisture content of your firewood, but are they a necessity or just a novelty? Seasoned firewood is considered to have a moisture content of 20% or less.
To test your firewood, simply push the pins into the wood and wait for a reading. Remember, don't just stick the meter into the ends of your firewood. To get the most accurate reading, split the wood and test the center. The center of the log will contain the most moisture.
