This is a playground our kids have long loved. Here's a poem to help you find the cache:
Near base of ramp ,find switch for light.
From there, see slide and tree.
A bunch of digits stand around,
Numero sept is key.
Beyond it, you’ll find living Y,
And now you’re near the end.
A tiny vessel overhead,
Well done, my clever friend.
NOTE: Tweezers or small tool could be helpful in retrieving log from cache.
