it is amazing way to travel into unique places and to learn them through experience of local people. You become a part of that country. You will never get such experience if you travel through tourist agency, and it makes this network outstanding!

Music - very individual and depending on my mood Movies - Some of my favorites - Fountain, Interstellar, Gipsy Time, Stalker, Brat and Brat-2 (last three are Russian movies) Books of Strugatskiys' Brothers (this is science fiction)
