We once had a power outage after a hurricane (1985) - no power for almost 3 weeks. I was very happy that I had knowledge of the 'old ways' learned from my grandparents and parents and we did just fine. The kids had clean clothes and a hot meal every day. And since I was one of the only people who knew where the ice house was two towns away, I made an ice run for our family and three other families twice a week to bring huge blocks of ice to set inside the refrigerators to keep the food from spoiling. It's a good thing I planned ahead as one other thing that doesn't work without electricity is the gasoline pumps.
It was that memory that was running through my mind when ATP didn't work. I was picturing a really big weather event in Texas. Glad I was wrong.
