Thank you for posting the picture, nice bear and nice hide. Congrats!
I know all about what you speak. When I guided for coastal grizzly in British Columbia it was the same thing in the fall........... they were feeding on salmon and there is no way you can eat that meat.
Conversely, where my wife and I live and outfit for black bear, the fall bears have been eating natural vegetation, alfalfa, oats and barley all summer, followed by berries in the late summer and early fall. The meat from these bears is excellent.
One of these days I want to try for a brownie in western Alaska or perhaps go to Russia and hunt on the Kamchatka Peninsula. I have hunted grizzlies in BC where they are grizzlies one minute, walk a few hundred yards, cross an invisible boundary and become brown bears in SE Alaska.
