I will pray for this man. The cold can kill at that temperature, the only way to survive it would cost over a thousand dollars in the gear he would need. Is he suicidal? Because this is one way to kill himself. I realize no one here believes in intervention against a persons will, but if the authorities were anonymously notified at the time the temps get to deadly lows, and that he is in the forest, to do a wellness check people would know he was there, they might save him. I will pray. Loss and pain and depression can make a person turn their back on the gift of life we are given.God gives us examples and opportunities to help one another, if a person refuses that help, all that is left is prayer. I pray that he comes to his senses.
