I am no expert on hydration and am only repeating what I heard so take it with a grain of salt. I was watching a college football game where a lot of the players were cramping due to dehydration on a hot day. The announcer said that you cannot get hydrated the day of the game but that it takes days to get properly hydrated. So drinking the day of the hunt may not be enough.
