A guy I know hunts Alaska every few years, been using the same guide for 20 years. But his guide eventually retired and he was booked with a young kid. He was pretty skeptical but kept his doubts to himself and watched the kid closely.
Didn't take him long to see that there were all kinds of little things that the kid did were just like his old guide did, right down to where he hung the necessary roll of camp paper. It was obvious that the kid had learned ropes under the old guide.
But the kid did something that the old guide NEVER did. Eevery time he stopped to get out the binoculars or spotting scope, he would sit down in the middle of a patch of wild blueberries. Jerry tried to see if it had anything to do with the style of camouflage, or if the low shrubbery broke up his outline. Finally he just flat out had to ask the kid. The answer was short and sweet, "Grampa hates blueberries. Me? I love 'em!"
I've never had a persimmon, something I hope to correct before I get too old.
