Oh, that made me laugh out loud! Over the years, I think I've become much better at hiding mistakes than building guitars.
I did consider a plug but for that small of a hole, with that grain orientation, it would crumble like a cigarette ash unless I made a larger plug. And making a small booboo into a large one just feels wrong. What I'll do, is find a similar piece with regards to grain and markings and cut a scoop with a palm gouge. I'll take a scoop out of the area surrounding and including the hole, (previously filled with sawdust), add a dab of titebond and press the replace scoop into place. Since the surface of the scoop is larger than the underlying body, it tends to hide the glue lines better than a plug.
As far as welcome to being you old buddy, a few observations come to mind. One, based on your avatar, we look a lot alike. And I've just heard recordings of your voice and we sound a good deal alike. You live east of the large city on the east side of MO, and I grew up east of the large city on the west side of MO. My son grew up in St. Luis.
But I've never driven a big rig.
Cheers!
