Its been mentioned before, but just be smart and prepared.
I too hunt Grizzly country along the Yellowstone Ecosystem. I do not bivy hunt however like some of the others so I cant offer much advice on food and camp prep. I can offer advice on your head being on a swivel and allowing your senses to be alert. Try to stay with your hunting partners. My group will separate a little bit depending on where we are, but that can be a bad thing. I carry bear Spray as well as a Glock 20 (10MM) with 200gr hardcast bullets. I prefer a chest rig for this handgun due to the fact that its close to me all the time and I do not have to worry about it getting in the way of my waist belt of my pack.
Obviously hiking in in the dark you want to make minimal noise, but when we hike out in the dark we make alot of noise. We even have bells thats we attach to our packs for the hike out or when we are packing game out. We do not leave game over night unless its an absolute must because of weather or terrain. If we need to leave some meat behind we will try to get it to the nearest trail at least a 100-200 yards away from the carcass and hang it high. We also try to find a spot that we can see it from a distance.
