One thing I have noticed is that the rut seems to have already dropped off every year by the time the archery hunts start out there. I live close to the unit and go out every year just to photograph the bucks. During early and mid November I typically see 30-50 bucks a day, and at least 5-10 are dandies. Then, starting in late November (Right about the time the archery season opens) all the bucks kind of disappear. I see maybe 5-10 per day, and absolutely nothing worth shooting. I've heard of a lot of other desert archery hunters complain about this. Personally I think the deer rut earlier and end sooner than most of the other mule deer herds in the state. This is my best guess as to why you are struggling to find the big bucks. They ARE there.
