in my experience, they tend to disappear from the open when the wind is howling. if you're hunting open sage country, not a bad day to do something else. between deer going into hiding, and the fact shots tend to be long in that country, its just not the best day to hunt. (long shots and a 40 mph wind is tough, i dont care who you are) of course, if your hunting days are limited, you just have to make the best of it.
