There is a plenty of good books for children these days. And one of them is "Oh, wie schön ist Panama" by a well known German author, Janosch.
If you haven't read the book yet, you can do so now! The book is hidden in a mailbox on the posted coordinates of this geocache. (There is one German and one Slovak copy there.) I hope you enjoy the story and if you really read the whole thing, I can guarantee you that the final coordinates of this geocache will be revealed to you!
