Hard work pays off in the mountains of the Yukon on a caribou hunt.

From Greg McHale:

"Brent, Greg's father, is looking for his third Dall's Sheep. In his early 70's, Brent's positive attitude and determination are that much more impressive. In Part 4 of this four-part episode, Brent and Greg get on a band of rams, but are they successful? Things wrap up when Karl and Greg locate a real character Mountain Caribou."
