If you get up on Mule deer they tend to run a ways and stop and look back; that is when many of them get nailed. Have hunted for many, many years but, for deer Mulies; for a long time there were not Whitetails where I was living but they have moved into many areas now. Yes, they are a lot spookier than Mule deer; I really don't hunt deer anymore usually go out elk hunting though. Like Jill I have deer in my yard on a regular basis, mostly mulies but in the last three or so years Whitetails started coming in. Was picking apples the other day and a 4x4 Mulie came down and was observing; started throwing apples at him; when I would hit him he would shrug it off and go eat the apples.
