Couch Surfing

Here's one of the things we're going to check into:

What is CouchSurfing?

CouchSurfing is an international non-profit network that connects travelers with locals in over 230 countries and territories around the world. Since 2004, members have been using our system to come together for cultural exchange, friendship, and learning experiences. Today, over a million people who might otherwise never meet are able to share hospitality and cultural understanding.
Our mission as an organization is to create inspiring experiences: cross-cultural encounters that are fun, engaging, and illuminating. These experiences take many forms. CouchSurfing's initial focus was on hosting and "surfing" (staying with a local as a guest in their home). Alongside these core experiences, we now also facilitate a growing array of activities and events.
We have a vision of a world where everyone can explore and create meaningful connections with the people and places they encounter. Each CouchSurfing experience shared by our members brings us closer to that vision.
