I put a game camera up to see if I could see the bear/s. Maybe the LED lights that come on at night made them suspicious. Or maybe they could tell that I was up and down the tree. Eventually, I saw some racoons on the SD card, but no bears.
I have had hundreds of bear pictures on game cams.
If anything they are curious about them and have bitten more then one.
If your not getting pictures of bears it is because they are not walking in front of them.
