Natural disasters?
1) Tornado, High winds that take down our trees and power lines, along with the heavy rain that could infiltrate the basement.
2) Bad winter weather: heavy snowall, super cold/windy blizzards, and/or ice storms. Again – downed trees and power lines, plus being unable to get up our driveway which is a fairly steep hill. Lack of power means no heat, despite having a propane source and the furnace fan will not move the heat through the house.
3) I guess it all comes down to – Power Outage.
