As a seasoned black bear hunter many folks have given you great advise as usual. Molasses or liquid black licorice are a winner as well as spreading some strawberry or blueberry Kool-Aid packages around your bait site. Using a rifle for your first hunt is a great idea, seeing a bear up close for the first time can test your nerves and last but not least.........as big muddy mention, any extra pair of under wear on your person is another good idea, they are know to climb the tree your sitting in out of curiosity , LOL
Have a great hunt, good luck and look forward to your report
