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.
The moisture content of the wood varies with the relative humidity of the surrounding air, as this chart shows. Once the wood has been dried, the moisture content never again rises above 28 percent (its fiber saturation point) from the effects of humidity alone. For this to happen, the wood must be immersed in water.*.
