Now that I am looking I can't find a picture, but trying to visualize where I want to shoot if I see one this fall in NY. Actually, gonna be looking to find one. [8D]

Mid body, just behind the shoulder, but make sure you don't hit the shoulder!!! It's much more massive than a deer's shoulder.

Check this out.. It tells you everything..

In the lungs.

Broadside - let the near leg clear forward and use the opposite leg for line of site. This offers an unobstructed shot to the vitals.
Quarter Away - again use the opposite leg as the line of site and drive her home.

These are your best shots on a bear with a bow. While the others can be done they are risking due to the large shoulder area of a bear. A liver shot bear will die but is not much fun to track...so quarter towards are very delicate affairs with bears and bows. One look t the provided anatomy link of a bear will show you all you need to know.

Aiming mid body on height will put you in the vitals.

Enjoy and good luck.

thanks skeeter7MM gives me a place to judge when shooting 3D to be sure I can hit the spot come time! [8D]
