In Irish folklore, the leprechaun is the cobbler to all the little people, he makes pretty little shoes out of leaves for all the forest folk and they pay him with a shiny gold piece. He is a mean old buzzard though, that leprechaun, and he will never spend a penny of his treasure, prefering to hoard it beyond the grasp of all his faerie chums. (As luck would have it, this is only thigh-high for humans.)
As elusive as he is crafty, very few people have ever seen a real-life leprechaun, but if you do happen to corner him at GZ, he may grant you three wishes.
You've probably already guessed what the cache container is; it is not going to make you rich, but hopefully it will make you smile.
This has to be a very small container, as you will see, so it is just a scrolled logbook (regrettably no room for swaps, apologies). It may be sensible to unravel and sign the log on the bench in the nearby park. Please replace the collar and return the cobbler's haul with the black side outwards as found.
Wheelchair accessible given a shallow kerb.
