I'm going to have to 'fess up sometime or other. Normally, it's not hard to remember the food bag, which I tie at the base of a tree. One of the beauties of the Ursack is I don't have to entertain the locals with my ridiculous attempts to bag a tall tree limb. We get up, we eat, we pack up, including the Ursack. Easy.
But in this particular case, we had eaten breakfast, and instead of breaking camp, attempted to summit a nearby peak. This particular bag was about 100' away from the tent site, out of sight, and apparently out of mind.
The route didn't go, so we came back, broke camp, and left to try another peak. Umm, without the foodbag, as it happens. What can I say? I'm 62 and forgetful? Thank goodness for the huckleberries.
By the way, good idea about not leaving the register in the car. I hadn't thought of my home address on it pointing the way to easy pickings.
