I have hunted Wannacut a lot, both as a child and as an adult (younger adult, back in the 80's). I never saw any bear in that GMU. I am sure that there are bear in there, but not as many as in other places around.
My cousin, Butch, always took bear, every year. But he went across the Okanogan over to Okanogan East and Sherman, especially the Lost Lake area...
