Wouldn't bother with apples unless you have 1,000 lbs to dump

not worth the weight to pack and will be gone in a mere few hours. I've watched a bear eat 30 lbs or so in a few hours . Why are they cut up?
Dump the salt and use some scent like apple oil, molasses or vanilla. It's not required to add scent as the salt alone will bring animals in a few days . Secure the cam very well animals like to screw with cams and nothing worse to hang a cam for that long to only have spun around tree or eaten by a bear after a few days. Hang it pointing north, use lithium batteries and the biggest SD card it can hold .
