Glad the little tyke made it. Glad the hounds made it too. Not sure who saved whom, but what does it matter. A win is a win.
With all respect, though, I do have to ask the skeptical question: 21 hours to search a one-mile radius? A SAR dog should take you from A to B in about half an hour, AFAIK. Even a focused ground search should cover that in a lot less time.
But I'm not a SAR expert, so I defer to wiser heads in this group.
