On behalf of sbook.ch and the winning class of our sustainable mobility contest – which raffled a guided tour of the Transportation Museum in Luzern – I would like to thank Marco Piffaretti for gifting us with such a wonderful day. With great generosity, Marco has dedicated his valuable time to us and has been able to organize a tour by catering the need of a 5th grader, even though he is used to interacting with slightly older interlocutors. Once again thank you, Marco!
