A student wrote a note with words from Mozart and placed it in a geocaching box after unsuccessfully searching for the "La Fira" geocache. They then found the Can Mercader geocache, where following clues led to discovering a plastic box with a geocaching logo inside which they left their note and a coin.

1. Preparations: First, I wrote a note to
put it in the box. It was a sentence in a
small paper with nice words of
Mozart.
I went to search the Geocatching of “La Fira”, but I didn’t
found anything so finally I decided to went to search the
Can Mercader one.
After searching the clues, I could find a plastic box with the
logo of geocatching, where I left my note and one coin.
