It's good to hear that you have power; I've been following the reports of the aftermath of the storm because it reminded me so much of a few years back when a hurricane hit the inland community where I live.
We were without power for 12 days in August. I remember it being so quiet that you could hear helicopters above our neighborhood surveying the damage. Every traffic light in the entire city was out for a week. Very few gas pumps operating because there weren't enough generators. People standing in line for hours to get a bag of ice. In a word...miserable.
I was totally unprepared and had quite a few vials of insulin on hand at the time. I did the best I could with gel packs that I had previously frozen. When the local pharmacy opened, I went to see if I could store my supplies there - no luck. The only thing I could come up with was Frio pouches and I returned it to the refrigerator as soon as the power came back on.
To my surprise my insulin survived but it was stressful. I do keep a kit now with all my most important papers in a case that I can just grab and go and diabetes supplies enough for a few weeks. Beyond that, I would hope that I could just travel out of the area to get what I need or at least make it to the Red Cross station. That's what they kept advising here after the hurricane.
