I use an insulated soft-sided lunch bag for various communications devices, batteries, leads & even my lunch. This morning I went to get a lanyard with four different USB drives on it, last seen in the tucker bag. Couldn’t find it. Drove to the Shed venue, wasn’t there either, nor was it in the car.
Eventually found it in the tucker bag UNDER a folded sheet of A4 paper that was, in that less-than-perfect light, the same colour as (and masquerading as) the bottom of said bag.
