I found it in the washing machine. Which doesn't make sense. Knowing it was missing, and looking for it everywhere, I took all the clothes out of the hamper a few days ago and felt around all the pockets and did not find it. From any logic, I could just as well found it on the roof.
But there it was... I've taken the memory card and battery out and I'm letting it sit to dry for a couple weeks. Maybe it will work after that and maybe not. And maybe the memory card and battery will work and maybe not. No rush since I have a new camera, but there are pictures on the memory card and I would like to get at those.
In one sense, it is good to have a mystery solved. On the other, it is sad to ruin a camera by carelessness. Fortunately, the cost is not a problem. And the replacement is identical, so there is no learning curve involved.
I've taken more pictures with the replacement, but I am too worn out from preparing taxes, Binq's vet visit and sorting out general clutter to process them today. I'll catch up.
