I hear this Question almost daily from new landowners nearby. It is amusing how Urban folks always think calling 911 will provide instant response! Here in the most rural of 67 PA counties we have usually ONE state trooper on duty. Bottom line: we are responsible for our OWN safety and the safety of any chickens, calves, and other critters. So, I tell rural residents they are on their own.
I understand the new city folks are conditioned about: "guns are bad" and never needed to be their own First Line of response in case of need. Well, Times and terrain and situation CHANGE in the Rural World. That is why I am usually full up in my shotgun training classes. All finally see the "light" and most go for a homestead 20 gauge pump shotgun and right ammo.
We have become a nation of Urban "Sheep", but once they "Move to the country", they need to adapt to new think and a reliable shotgun. Every one of my friendly students gets a shotgun for their rural property and some come back for a handgun and their CCW. Freedom still exists....and NONE will Ever Vote to give up their newly acquired firearms. See, we CANNOT convince folks, but we CAN convert them, one by one. Amen.
Be well.
