Colin, for your reflection. I posted this previously, but I lost a camera to thieves sometime in the past year. It was on a 15-month soak, very deep in the Idaho mountains. National forest. 50 miles from the nearest town. 5 miles from the "main logging road." 3 miles on a trail from the nearest logging road. At least a 1.5 hour hike in to the spot. Bolted to a tree, in a bear box, with a cable.
Thieves broke the lock, took the camera, but couldn't take the box, so they left that.
A bear box is better than nothing, but determined thieves will get it anyway.
