We drive them around our place and the deer just stop and let us go by. We have shot/seen some nice 8 points on our place also and some times we park next to the blind. I think it depends on the deer, some deer are spookier than others and some think they are the biggest badest thing in the woods. I think the more activity there is on the property the spookier they will be, they will not stay if they get interupted all the time.
