There is a chance of rain this afternoon. We can only hope so. Little Jerold may need a serious drink right about now, even if he just has to hold his mouth open and point it towards the sky. He can still survive for awhile if he can find pockets of water to keep him hydrated and get a drink now and then. The key to surviving is access to water, more-so than food.
These guys are running out of time though. 72- hours in now, Jerold's going to be getting really weak from the lack of food and nutrition. He most likely has exerted a huge amount of energy running around in circles and climbing up things and over things. After a certain point, he's just going to sit down and not go anywhere, he won't have the strength left.
They need to bring in 500 more volunteers and send them out into the areas that either haven't been searched or have been lightly searched. Any of the lifelong residents, hunters and hunting guides familiar with the area, and any ranchers that have run cattle in that area should be the top pick as potential searchers. They already know the place and how to get around. If nothing else, they can have them run up and down game trails, primitive trails, and old logging roads just to see if they can find any trace of him.
The can be somewhat selective who they let in as searchers, but they need more of them, and they need them NOW.
