I’m not sure where you have the best chance for a cinnamon (brown phase) black bear. I took a nice old barren black sow in Alaska on the Kenai Peninsula. It was a boat based hunt. I saw 42 bears in 3 days. Not 1 cinnamon. We fished mid day and bear hunted mornings and evenings. It was a fall hunt, so the hair was long and beautiful!
Mine measured 5’10” nose to tip of its stub tail. 5’7” toe to toe.
Actually I read that South Carolina has some of the record size black bear in the country. I can’t believe their hair can compare to those in Canada or Alaska though.
