It turns out a squirrel put it there as part of its overall winter-proofing strategy. Good job.
What are you good at squirreling away? How do you maintain a balance between saving and stashing for a long winter and unhealthy hoarding?
Being without a home base, I cannot afford to hoard. But I love mushrooms and that’s one thing that I can see myself saving in a tree branch for a rainy day.
