The 19th hole is a golf term for a place to kick back after a round of golf. I believe Charlie Fox's little fishing shack was the 19th Hole.
And coincidentally, that is pretty much where I-81 crosses over the creek.
In many conversations I had with Charlie before he died, he often told me how they straightened out (and ruined) the "turnaround" or switchback as he called it, when they built I-81.
Ironically many moons, a go I caught my biggest Letort brown (about 24") under the I-81 bridges on a crayfish.
