Interrail this summer?

As i preveously announced my crazy plans for driving around the balkans - things makes me realise that i'm evidently not experienced enough for that yet. Nether will i be in one year. A good idea to substitute, as proposed by Mari, is to Interrail! It's cheap, it's nice and it'll be exiting. Maybe combined with some hitchhiking? We could go as many as we want, we could travel where we want and see a lot of the world. I could easily afford two full months of interrail time! Sleeping at stations, seeing the balkans... Brilliant idea!
