Deer (mulies & blacktails) don't like heavy wind, check the back side of the mountain (out of the wind), below the ridge or at the base of trees where they can see a ways and have a ready escape route. GOOD binoculars and a spotting scope are generally your ticket to success. The bright side is strong wind will often obscure your scent and cover noise. (and it depends on temp., weather, moon, pressure, etc)
