** The cache IS at the posted coordinates **
However, since this is a challenge cache, you must fulfill the Logging Requirement before posting a Find.
I had some fun racking my brain for ideas for new challenges over the last few months and this one came to mind. It took some work to get it done, but I hope others also enjoy the challenge.
To log a find on this cache, you must:
- Find 1 cache of the size "Large" published during each year of geocaching, from 2000 to the current year
That's it! Good luck!
