Cucumber's and Copperhead's

Back in Kentucky one year while Dad and I were squirrel hunting up on the ridge, we both suddenly got a strong whiff of cucumbers. It smelled like someone had pealed a truck lot of cucumbers.
Dad said “Son, you smell that? Do you know what the old timers say about the smell of cucumbers in the woods?”
I answered, “Know Dad I don’t, what does it mean?”
“It means there are copperhead snakes nearby.”
I said, “Now do you really believe that Dad?” Which I knew he did not because Dad never believed in any of
Those old sayings, or planting by the signs.
He’d say, “Now son those are just a bunch of old wives tales.”
Well then Dad what is it then?
I don’t know son.
We had walked about 20 feet, when Dad pulled up his gun & fired two shots. I was looking for the squirrels, but all I could see was two dead Copperheads.
Dad just turned and said, “Maybe that tales true son.
