Isn't that the case all over, even in urban environments? The saying, "When SECONDS count, police are on MINUTES away, and will be there shortly, to take the report".
So for a H.D. situation, everyone needs to plan accordingly, no matter where they are, city or country.
I know in my case all emergency situations: police, fire, first aid, disaster, etc. revolve around what I can accomplish myself. There's no plan to have help from any of the above, and my thoughts are, "when they get here, they get here". I've planned for H.D. situations from all areas of the house and property. Calling 911 isn't part of the initial plan.
