Thanks for the link, I updated my first post. But, do you know if the Lone Pine boxes are the same, I could swear that the boxes up in Whitney Portal were smaller, but maybe I only saw the ones for hikers, and I know that the ones up at Horseshoe were smaller. (probably the 18x18x50).
The Nut/Wrench did not cause any problems for us last year, but i'd love to see a bear open a properly closed box.
