The last Grizzly came on May 20th. I stopped baiting for over a week and that's all it took for the Grizzly to loose interest. The stand is not very close to any rivers and that's where most Griz are headed.
Three years ago I had an injured Grizzly come to the bait stand. I ran him off twice, then I had a Black bear try to come in. The Griz ran off the Black, so I decided to let the Griz eat the bait. After all, how could I leave if the Griz was guarding the bait stand. Once I saw all that happen for myself, I just give the bait a break, but don't give up on Blacks even if Griz are in the area.
