I've hunted 4b pretty regularly for deer and have videoed alot of elk in there, my little brother missed a good bull in there 3 years back. In the late hunt, hope for snow and look in Pierce Canyon, can be rough but very productive.
I was out Labor Day Morning in white mountains, and got in to 4 bulls, one was screaming, the other three hanging out whistling, they kept it up until almost 8 am. I never got to see the screaming bull but of the other three one was a small 5x5 the other two low 300 bulls. Early that morning driving out I saw 2 bulls cross the road, both decent bulls, one maybe high 370, hard to tell as they ran across the road.
