Thar has come up a couple times now, but I would say it is more slang than misspelled... how else would you say "that thar over yonder"? Well, I wouldn't say that at all, but you know what I mean
But I have singled out thar anyway for its repetition and also spin and scope and maybe
Now, they haven't lead me anywhar,,,,
So a couple "WAGs" would be a simple monocular and/or a night vision scope, but those guesses don't hold true to the "if you know what it does, you know what it is" clue, as they aren't really broken apart that way. And the dang thing is a modern toy now. That one really has me stumped.
So............ that's where I'm at. No closer today than I was yesterday.
