I think it depends on how you use your cameras.
Bingo.
If you check your cameras alot and leave them in the same location, I think you educate them.
Bingo, Bingo.
I will hang them in areas that I am not hunting much
Ahh....this is great!
I don't put trail cameras where I want to hunt. I put mine on my mineral site....and use it only for inventory purposes. Look at it this way....
If you put your trail camera out where you hunt.....that deer doesn't care whether your checking your camera.......hanging a stand.....clearing shooting lanes.....or scouting. ALL he knows is.....you've intruded his house, AGAIN.
So....do they get educated? I'm sure they do. Are the cameras doing it? Hell no. WE ARE.
