Leave the bear tag at home if you are over bait. Same thing with coyote hunting with a smaller than .24 (.223 for example) with a big game tag is a violation. Heard it first hand from a gamie. BS to be sure but not worth the hassle or to lose Master Hunter status, etc...
I wouldn't worry about leaving my bear tag at home, just don't shoot a bear over bait. What if you see on on the way to your hunting area? I would never leave my bear tag at home if bear season were open.
