Thanks Ray – I checked every voltage I could and nothing was amiss, so I put in my other Pi using the same SD card from the bad one and everything worked like a champ. I was back up and running in minutes.
I hate lightning. It can cause so many strange things. Several years ago, I had lightning strike a tree outside my home (in another state) and the lightning traveled into my house via the ground line taking out several things, including hopping over to the RG6 coax line and completely vaporizing the inside of a notch filter.
