I have to say, a little something died inside of me... After spending weeks and weeks plotting and planning the puzzle for Cicada 3301 (GC68G19) - working out flowcharts, and all the different intricacies - the puzzle was solved and the cache found in just one day. One day!
That is all you need to know about the puzzle-solving prowess of one Skinaglow60. She has become my go-to PAF (Phone-A-Friend) when I'm stumped on a Mystery cache, and she has come through for me more than once with the needed solution.
She is also a force to be reckoned with when it comes to the coveted First-to-Find. Her secret weapon? A Pink Ferrari! If you're not fully on your game you stand little or no chance of beating her to ground zero.
Any cache dedicated to Skinaglow60 should be a nod to both her puzzling abilities, and to her trusty pink Ferrari.
So, Skinaglow60, here is your puzzle. I hope it challenges you for slightly longer than one day.
Have a look at Skinaglow60's Pink Ferrari... she can really ZIP!

Enjoy!
