Actually, it did turn up.
The longer version though; I had changed planes in SEATAC airport, and realized once on the new flight that my Boss70 was not in its pocket. So I sat there in grief for about 10 minutes, wondering if it had went MIA in the Eugene airport (where I had spent the night), or the subsequent SEA airport. With the airports, when it's gone, it's gone. :-(
Turns out it was in the wrong darn pocket - which is how I'm empathizing with Bilbo, lol.
My multi-tool is always in the right pocket, with the Boss in the left pocket. But not carrying my usual multi-tool (e.g. airport security), for some reason the Boss went into the right pocket after I went thru security. A simple change, but literally the last place I'd check for my flashlight. :-/
