Knot in the wood.
We got a good giggle out of this cool cache. SupremeMe was the first in our group to see it. I laughed and commented that it looks like a boob.
It appears as though they have painted where the branch was sawed off so that it matches the tree. The container is painted the same color. I love it when caches are creative and are right out in plain sight!
