While Stephanie and Peter Hudson were out enjoying their trip to Europe, Stephanie saw this at the airport in Zagreb, Croatia.  It’s a rather clever coin collector for the Rotary Club (Klub) Zagreb Centar.  Rather than stuff it in a drawer upon your return, you can toss the local currency into this installation on your way out of the country and help Do Good in the World.

Klub Zagreb Centar was founded 22 years ago and is very active in both Community and International projects.  The description of their Club is “Rotary Club Zagreb Centar invests long-term and strategically in charitable projects financed by donations from its members and other donors.”
