He never stopped trying, and his family did not give up hope. "We knew he was out there," said Jeremy Penaflor.
The search party went out again Saturday to look for the 72-year-old, and this time the group was about half the size of the original one. But someone beat them to Penaflor.
A hunter called the sheriff's office in the morning, saying he and his large group of friends could hear a man crying for help from down in a valley.
The cellphone connection dropped out again and again, before deputies could note his location, the sheriff's office said. They instructed the hunter to call 911, and the operator locked in on his GPS coordinates.
Penaflor's cries led the hunting party to him. They cut poles from trees and affixed their coats to them to fashion a makeshift stretcher to carry him out.
Rescuers met up with the group hours later, as they heaved him up a steep hill. They called a helicopter to ferry him to Ukiah Valley Medical Center.
Hugs and tears
When his family saw him, no one spoke, Jeremy Penaflor said. "Just hugs. And we were in tears."
He released a photograph to the media, showing his father in a hospital bed, smiling and giving a thumbs-up.
No more hunting for now, the son said.
"If he decides to hunt in a couple of years, that's fine. But we joked around and said let's make it a camping trip."
If he goes out again, his son wants to be with him.
