My family went to hit the beach.
The local one we soon did reach.
We saw an object out of place,
Used to make a different space.
My mind recalled a simple song,
One we've sung for very long.
It is a song a child will learn,
And ends with a surprising turn.
A cache I left behind to find.
And hope your name will there be signed.
If you find it and enjoy your time,
Perhaps you too can share a rhyme?

To check if you have found the spot,
Enter the coords you've got:

As with any of my puzzles, I'm happy to provide nudges if you need them and let me know what you've tried so far.
