The explosion you hear in the opening seconds, that nearly caused me to drop the phone, was a transformer somewhere nearby. Another loud thing was a great tree falling in the woods somewhere to the left. There's a creek down there and the ground is too wet to hold these big trees in heavy winds. Every year a few more fall. The more I listen to this, the more I suspect there was a baby tornado nearby. That weird wailing noise midway through..no clue.
The power was out when I retreated from the deck. Five hours before it was restored. Even at 5:00pm it was too dark for much but napping.
