Squirrels are the ultimate cachers, don't you think? They hide thousands of nuts every year, caching them so they can eat them later. They sometimes are quite devious about this, using all kinds of tricks to prevent other squirrels from finding their stashes. For example, they'll fake-hide a nut while they know another squirrel is looking, and then go actually hide the nut somewhere else. They try to camouflage the hiding spots with leaves to make it look like there's nothing out of the ordinary there.
And here's something I learned recently by seeing it in action: squirrels don't just hide nuts, but they'll also hide mushrooms up in trees. So next time you're walking through the forest in the fall, keep an eye out for mushrooms in unusual places.
The easiest access to this cache is waypointed at the end of Ray Canie Blvd, off J.V. Bonhomme Blvd. The cache itself can be gently opened by splitting down the middle. Have fun!
