I've had my camera out on a heavily used trail for over a month now and the only pictures i've got is of two little bucks and does. I check my camera every week or two and i have deer cane in front of it, and the little bucks and does like it and they keep coming back. I just can't get any big bucks in front of the camera. I know there is big ones around because my dad has seen them bush hogging and i've seen one. Any tips?
