Around 15yrs ago. The wife, myself & our 85lb Belgian Malinois/German Shepherd X, name of[Summit]. Were nightime catfishing along the Iowa. We had a Coleman Lantern for light. It cast light in a 30 diameter, around us.
Our dog, was on a 16' chain, anchored to a tree, off the trail by us. Were fishing...Suddenly, Summit goes on alert. Then he lunges up onto his hind legs. Chomping the air, visiously. I whip out my Fillet knife, as well.
Then out of the darkness, came the local town freak. Known as the "elf-man". This nut-job, actually thinks he can "talk" to the animals....[one with nature]

...yah, OK.
I confronted him, told him to go away. He insisted! on standing a ft away from our dog's snapping jaws[summit, wanted to eat, this idiot]. He told us, "It's a FREE Country", & that he can "Communicate" with Summit.
He wouldn't listen. I said, "Fine, if he slips his collar, your on your own. I won't pull him off!"

He finally turned back into the darkness, towards town.
