A couple of years ago, while hunting deer on public land, I noticed movement on the next ridge and focused my binocular on the spot, about a half mile away.It was another hunter, lying prone, his blaze-orange vest obscured by his pack. I was alarmed to see him looking back at me not through a binocular, but through the scope on his rifle. I inched out of rifle sight, my cold shiver replaced by an angry flash. For better or worse, I resolved to confront the dude who was aiming at me as if I was an enemy combatant. Or a deer.
