Don’t worry I am. I always have a plan B and C,D,E for that matter. You don’t take things lightly here in the boonies. We just can’t pop down to the store and get the things we need. Some common things I use can only be had by ordering and shipping or a 3 or 4 hour drive.
We are in the same situation. 75 miles to the nearest gas and groceries. It has already started for us, Our grid is going down for a couple days at a time every couple weeks average. They are now stealing our rural power to make the cities comfortable. But we have been small scale off grid solar/wind for years now. Our minimum priority is only food refrigeration, over the years we have learned to live without needing grid power for anything else. But we are fully set up and ready to process foods for long term storage without refrigeration when it does come to that and can live without any power at all.
