As I have wrote, it costs you 80 € if you travel without ticket in Helsinki public transportation. Ouch. A couple of day ago I found this great Facebook-page where people warn others about Smurfs. They write on what train/metro/tram they are and where they have seen the Smurfs. This is really great idea! It's in Finnish, but you can use Bing to translate. Sharing is caring. I love this!
Check out SMURFFITUTKA
Ps. People are planning on making an Smurf-application too. This way you could follow where the Smurfs are going real time!
Finnish people are funny :D
