I'm actually doing a road trip accross the US with a friend of mine and it's by this way we discovered couchsurfing. We are traveling by car during four month and half to discover the different states, cities, national parcs aso... Thanks to couchsurfing we can meet people that live here and their habits, customs aso... It's a great experience because we can learn more about the "real" life of the country and we can discover a lot of new things and places which are less known!! We can also share our experiences as Swiss with the people we meet :)
