Bosque Del Oso Bear Tag

[JZelk22]

Hey guys, was looking at hunting GMU 851 Bosque bear tag in the near future. Seeing that there are 3 options (O1R, O2R, and O5R), I was curious if anyone has experience in this unit during the later seasons running into bears during elk/deer hunts? Trying to figure out when the bears go into hibernation in that area. I would assume a bit later than the northern units of CO since it's a bit more dry and mild.
