I think the root of the problem is the transition from hunting with a gun to bowhunting. When I used a rifle, all but one deer I have killed I shot in the neck. When you hit them there they just dump where they stood. Who ever needed to learn about tracking? Even a well placed shot in the shoulder usually results in a very short run and easy tracking. My rifle made a small hole going in and a softball crater on the exit side so a blood trail was something that took little effort to follow. Now here comes the new bowhunter and he shoots in the back yard and does all he can to get ready only to make a marginal shot and then finds that following drips of blood is much harder than following buckets of blood.
