Historically, wolf trappers staked traps in the earth so that a trapped animal was stuck at a single location. This made it easier for the trapper to find his quarry, but it caused a great deal of stress for the animal. Stake-trapped animals often struggle so violently against the metal clinching their legs that they severely injure themselves. By not staking their traps, and by adding features like a drag with a coil spring and swivel - which reduces the strain from the pointed prongs when it’s being dragged - the red wolf program allows a trapped animal to continue moving and to seek refuge. In theory, this makes the trapping experience less stressful, both physically and mentally, for the animals. It can also make them harder to locate.
“Please take it off,” I blurted. The sight of the metal trap biting Ryan’s hand shot adrenaline up and down my spine. Even though he claimed it didn’t hurt, I still expected geysers of blood to spout at any second. Ryan paused, clearly taken aback. Then he grinned like a jester and doubled over in laughter at me. When he freed himself and slipped off the glove, a faint purple pressure mark wrapped around his fingers. He often demonstrated this to groups sans glove.
