I love to meet locals because it enriches your experience. I think couchsurfing is a good way to meet locals and the local way of life :-) I've get to know couchsurfing because a friend of mine hosted couchsurfers frequently and it was always a really nice and educational experience.

Climbed vulcano Momotombo in Nicaragua. But I hope to do much greater things ;-) Swimming with whalesharks!
