Couchsurfing is great as you get to meet the local people in a foriegn place that you otherwise wouldn't meet if you just did the regular tourist thing. So far I've met many great friends on couchsurfing, seen amazing things and had great experiences I'll never forget. I've also hosted a few people which has been a great experience, I love to show people around my home city of Perth, Australia. Couchsurfing is awesome!

apocalypse now, starwars, predator, aliens, the beach... Pretty much any movie by James Cameron, Ridley Scott and George Lucas.
