That was a couple of very large dogs and not doors ;-)
My house is on a private road with just a few other houses they would have to pass to get to my house so not to many people come down the road.
There is an emergency exit down a staircase, to the street below when the driveway is snowed in but that is not to convient for Burglars to haul away much.
The dogs start barking when some one is halfway down the drive way. We are the last on the private road and the neighbors are about 150 feet further up the drive way. Terrible drive way, part of it is a 30% slope and it can be a bitch to get up even in the summer with a shift equiped car. The engine starts going slow and they stall out.
