We make sure that there are no good places for people to hide to break into our house, so we can see anyone coming for a mile away. Our property if fenced on 3 sides with a solid fence, which obstructs the view of criminals from outside. We have an automatic locking gate, and a security camera pointed at the gate and pasture. We also have driveway alarms/chimes to let us know if someone parks or walks up the driveway. I have a pair of geese who patrol the orchard which is in direct path between pasture and houses. Each house (We were forced to buy this by our insurance company) is equipped with security alarm system and also bonus of having wired smoke detectors which alert the fire department of a fire immediately if we don't shut off the alarm in 1 minute or so. If somebady was invading my house I would set off the panic and the fire alarm. From experience, I know the fire dept. will be at my house in less than 3 minutes. Then we would go into one of our 2 hiding places in the houses. Where my law enforcement bro has the weapons stashed.
Humm...I just read my post. For a peaceful non-predator killing vegetarian I sound kind of paranoid. lol
