Next day I went back to the field and found the rangefinder right where my blind had been. It must have bounced out when I pitched it in. So, the story has a happy ending. I shot my geese and found my rangefinder. The only item of consequence I have lost this year is a spiffy snow camo ballcap from Cabelas that blew off my head in the field one day and disappeared into the snow (I couldn't chase it, there were geese coming). I lost my ghillie jacket for about a week, and finally found it in the field where it had fallen out of a decoy bag. Ghillie jackets, by the way, are among the hardest things in the world to spot once you lose them.
