High Country Muley Hunt Question

Hey everybody, Im a second year hunter and still have a lot to learn. Got my first muley (a doe) last year near Lander. This year I have a general tag and am living in Jackson. I have been out and about in the snake river range and the Gros Ventres since the season opened. However, I have only seen does and no bucks. This year the general tag is antlered only in this area. So what my question boils down to is how to early season hunt for bucks. I am in no need of a trophy, just a deer with antlers that will fill the freezer. In reading online, it sounds like bucks are hanging out way up high until bad weather or the rut. How high do I need to go? Ive read stories about people finding large muleys hanging out in alpine bowls. For some reason it is hard to imagine finding deer in places I would normally go to bag peaks. Anyways, it sounds like a much more intensive hunt (carrying gear in and deer out much further distances). However I am in good shape and will go wherever necessary to find some bucks. Itd be great to hear some suggestions of places that might hold deer in the area. Also, I have been getting out and in position before first light. I've read that bucks are pretty much headed to their bed site around that time and wont do much after. Does this mean that I pretty much have a 1/2 to full hr of good hunting when it begins lighting up, and then I will have to hope to stumble upon something, or kick up a deer from where its bedded down? Especially if I am gonna be way in the backcountry, I want to know if I absolutely need to be there before light, and if I am wasting my time after. In living in Wyoming the last two years I have seen many bucks, and I am sure they will start heading down soon, but I am eager to get out now and try and get a muley before elk season opens up. Any help, ideas, or spots to hunt would be greatly appreciated. Thanks! Jake
