I have realized that Alaska could be considered and exception in some cases but, I haven't been able to find any were in the regs that says what legal shooting hours are. I thought of this question Caribou hunting last year in August. Typically you figure 30 mins before and 30 mins after sunrise/sunset.
One other question when bear baiting which I am going to gear up and do this spring. Any one have in general the hours their bait sights seem to be more active than others? Guessing Dusk and Dawn?
