Once there was a boy named Rocketship Joe.
He called himself that, ‘cos he lived by this big silo.
Every night he dreamed of flying up to space,
This silo was his ground zero, his rocket base.
The little boy became a man, and grew to become old,
And this was the fable he always told:
Look to the cosmos, dream up high,
Though the greatest adventure is inside.
Use your heart's rail to sail up to the tales of the sky,
So you can find your sun, your one, your curved mind’s eye.

UPDATED 8.8.23: Vandals destroyed our cache, starting with the initial one which was on a pulley inside the silo (pictured). We reconfigured twice. Then our third adaptation was destroyed by the city who buttoned-up our beloved silo. So, we have created a fourth hide: it eliminates the swag and makes the cache a microcache but it preserves our initial aim: to have a cache and story attached to "our" silo (yes, it's a special place for us).
There is a hint (in the poem). It's much more difficult to find now. Apologies.

We are the Creative Adventure Family, with kiddos that are 8, 6 and 4 years old (Gem, Silas, Harlow – hence the name of this cache: The Gems in the old Si-Lo). Dad and the kiddos collaborate on all our adventures, like creeking, Sasquatch and ghost hunting and now geocaching.
Our goal is: EXPLORE. And, to cultivate curiosity.
By hiding caches, we hope to reveal places special to us and our adventures, secret places that we love.
