Small geocache hidden in the traditional way. But who is C3? Congratulations to Cache-Addict-Mel on a very fast first to find.
You are looking for a purple container. If you are right in front of a camera, you are probably in the right place. See the difficulty rating. Not my typical hide. Will add a little bit of a hint for every DNF.
What makes you think this is so hard? Are you stuck between a rock and a hard place?
