Sometimes, you get an idea about your next cache.
Then, after not finding a good location, the idea moves to a back burner. You almost forgot about it.
Suddenly, when you see the spot you know: that's it.
This can be as easy as a Park-n-Go or might take some time to find.
I'll start with a tiny hint; everything else would be a spoiler.
You're looking for a nano.
Yes, a tool will be required.
Please leave everything as you found it for a better experience for the next finders.
It does not matter if you're a geocacher or a surgeon. If you have the right tools, sharp eyes, firm hands, and luck your mission will be accomplished.
If you like challenges, you can get the cache without using your hands. Literally.
