in the near 8 years we have been in my home I have had people come down our driveway twice.
Once I happened to be driving in from work and I slowed and told them to get the Hell off of my land, they turned and left.
The other I heard the dog making a commotion and I came up from the basement to find two of them about 30 yards or so from the house. I went out on the porch and yelled ( not very nicely ) that the road was thataway (pointing in direction they came from) and they needed to go to it. They hesitated and I yelled again, they left.
I hate people coming back to my house. It is part of why I live way off the road, helps keep the riff raff away, but it sucks when I see the ice cream truck go up the street and can't get to it in time.
