This is one of the 5 caches that compose the series "Fill In The Blanks".
Make sure you take note of the clue inside the container.
When I wlaked down this road the other day, I saw for the first tim e a very little character that I would describe as a "Leprechaun". So I tried to get closer to have a better view of this miniature personage but as soon as I arrived at the spot where he was standing, he vanished in thin air leaving behind his little stash. I grabbed it and hid it somewhere else.
So if you are careful, maybe you will get a glance at the Leprechaun or ,at least, grab his stash.
The "Swags" are meant to stay in the container for others to enjoy.
NO SPOILERS please.
Enjoy
