Left it in a bag at the Agoura Hills McDonald's enroute home from Gallifrey. Discovered the missing bag when we stopped in Solvang for about 10 minutes.
No one answered it when we called it, but no one turned it in to the staff either.
Fortunately, I'd backed up the contents at least as recently as Further Confusion, and I pay the four bucks a month to cover replacing it.
However, it means no cell phone until I get said replacement.
Damn and Blast.
