I've hunted as many as 4 people in 20 acres before but that's on a mountainside where all the deer movement tends to be parallel with the ridge at different elevations so a person at the top of the ridge may never see a deer walking at the bottom of the ridge. For me I enjoy having friends to hunt with and if it means that I might have to share a nice buck, so be it. Sometimes it helps me to stay in the stand longer if I hear that someone else has seen something. (we can use radios in my State)
