Your story reminds me of .. well... me. In 1965 I bought a fox call direct from Burnam Bros in TX. As you said, one page of directions, no internet, no videos, just that it had to sound like a baby crying. Well I must not have heard the correct babies. Jim and I went to the river, set back to back and I started calling. Soon Jim started to shake, then I did too. We were laughing harder with each squak or squeel I made. WHAT KIND OF A DUMB A** COYOTE OR FOX WOULD COME TO ANYTHING THAT SOUNDED SO STUPID AS THIS. And none did. A big hawk did land in a tree not far away and study us so maybe we weren't quite as bad as we thought.
Also!... I had with me a .303 Brit that I "personally" ordered and bought out of the back of Outdoor Life. I guess those days are gone
That hunt was not exactly my best hunt but I still remember it and smile each time I do. Thanks
