I love the concept of couchsurfing. to get in touch with people from all over the world and spend a good time with them. I also wanna improve my english and like to get some good tips from people who are living in the city, where i'm traveling at!

That would be a long list... I could only give u a few examples: Music: Punk Rock/Hardcore/Singer-Songwriter Movies: everything's illuminated, igby goes down, imaginary heroes, moonrise kingdom, Star Wars iv-vi... Books: from irvine welsh, jasper fforde or douglas adams but there are many more
