Back in the mid 80's, 4 of us guys from work went up to Shiningtree, Ontario, Canada on moose hunt.......way back in. Old dirt road for miles, into a lake all the way to the end of that lake. A 150 yard portage into another lake and all the way to the end of that lake. It was damned remote. We set up a camp on the shoreline of the lake.
But before we wet, I packed a special extra piece of equipment. We had a dog that enjoyed playing tug-of-war with any piece of cloth, and while doing this she would make these gosh-awful growling and snarling noise that sounded like some deranged rabid animal. I had a small portable tape recorder, and I taped a long session of all these loud growling and snarling noises, leaving a 15 minute empty section of the tape at the beginning.
So the first night after our tent-camp had been set up we all sat around the campfire talking about the usual BS that hunters talk about around the fire, and I said I have to take a leak and went off into the total black darkness. I pulled the tape recorder/player out of my bedroll without anyone paying attention and took it with me. I turned it on and came back to the campfire. That 15 minutes of empty tape gave time for everyone to forget I had even left. Then all of a sudden, in the middle of the deepest, darkest Canadian wilderness came this horrible loud maniacal growling and snarling out of the darkness. Panic set into the camp as everybody grabbed knives and hatchets and anything they could to defend themselves. It was an archery hunt, so there were no guns. Finally, we decided to go out and see what vicious thing it was that was threatening the camp. So I put on the big brave John Wayne style act and led the crew through the darkness using just flashlights to light the way. When it turned out to be a tape recorder, I am not sure what kept those guys from throwing me in the lake.
