whitetail are whitetail, and that's all there is too it. the only difference between coues and eastern is the terrain in which they inhabit.
if you want to kill a coues, locate some heavily used doe trails and corridors that they travel in, then hang some stands in those areas, carefully considering the wind, and exposure, etc. wait till the rut kicks in and start hunting.
i've found that coues live in textured terrain with easy access to canyons and steeps. occasionally i've found them in the flat bottom land, and occasionally i've found them way up on the side of mountain, but for the most part i've seen them in draws with good browse that are near an escape route.
the habitual nature of the coues makes them easy to kill. it's the open terrain that works to their advantage, that's why i choose to hunt them higher up in the trees, where i can hang tree stands and get out the line of sight, just like i would back east.
