They will be in pockets as they are in farm land certain areas have better browser feed .. I live close and have hunted and watch mulies in the foothills here in Hinton area .. and also the mountains .. what you need to do is spend some Recon time in your WMU and note where you see pockets of mule deer and time of year as they will move where the first snow comes sometimes
and yes to deer being the same... just like us they like to be out of wind and in shade with water near by
