This cache is at the posted coordinates... NOT!
One time I saw this puzzle on online:
"Someone's mom has four children: North, East and South. What is the name of the fourth son."
So, what is the name of the fourth son? I don't know! Well, type the name into Certitude and you'll get the coordinates.
You can validate your puzzle solution with certitude.
