Almost everyone believes that bears come in at dusk and that is it. Go sit on the stand for the evening hunt. In doing so you could be missing out on that bear of a lifetime. Trail cameras tell the real story. Bears are most active during the Minnesota black bear season when it is coolest out. Some of the bears are most active in the early morning and at or after dusk. That does not mean they will not come in at noon. They do. The driving force for the bears is to put on as much weight as possible before it is time to rest for the year. The bigger bears like to play it cool simply because they are more apt to overheat than a smaller bear.
