I called and asked that very question, if I knew of a few gutpiles can I go back and bear hunt them??? Officer said NO. If I knew where the piles were it was considered baiting, If I stummbled acorss a new one and saw a bear then I could take it. If I stumbbled across a new pile and "sat on it" until a bear came... that would be considered baiting.
Now I just follow crows in heavily used areas, I don't look for piles anymore... I have not shot a bear this year, I have seen two this year but rules are rules and did not shoot.
