You can't bait here but my cameras are in bear country,mostly on springs or trails.These days,every camera I own has a steel box.They are worth their weight in gold.Bears have destroyed $800 worth of cameras for me and I had a tree fall on one and busted it up pretty good but I was able to repair it.
Once the box is lagged to a tree and aimed properly,I can remove the camera and put it back and it will be aimed exactly where it was before.I bears mess around it or stand with their feet on it,it isn't knocked out of position.
I get the regular steel boxes from camlockbox.com,not the heavy duty ones and have not had one problem since using them.I just don't buy a camera now,without buying a box.
It is impossible to hide anything from bears and at a bait site,with all the activity,I would expect trouble.Young bears are probably the worst,but I've had trouble with mature ones too.They are also good for chewing up padded tree stand seats.
