I watched my first two episodes on my PVR. It was the Barbary Sheep hunt and the Winter Mule Deer hunt. I have to say I like it. I appreciate the effort he puts in, the camerawork is pretty great and I don't have to constantly turn down the irritating synth/techno soundtrack that far too many hunting shows use these days. I'm not so sure about his culinary skills, however, as he burned the hell out of his onions when he was cooking that quail in the dutch oven! LOL!
As for leaving kills overnight. I prefer not to do it if at all possible. Getting your meat cooled down as fast as possible is probably the most important step to ending up with superior meat. But, some times that simply is impossible to do. The one thing going for him at high elevations is the very cold temperatures you normally have, especially at night. It gives you extra time and if you get to it first thing in the morning I doubt if you'd have too much problems with the meat turning sour.
