Couchsurfing is an international organization for travelers; for a couple of years we have hosted travels from around the world; we give them a room to sleep in, a place to bath and do laundry and usually they'll join us for meals. It's free lodging
We have never used it as travelers though. CouchSurfing - Greg Fahy
It goes hand in hand with group gatherings of Jeepers, etc. You go somewhere new and get together with locals instead of doing the boring hotel thing. You really learn the culture and experience it in a more enjoyable way. We've lived in New Bern most of our lives, so we often take our "couchsurfers" around town, the historical district, hiking, kayaking, etc.
This would be a good time of year to drive south towards FL; we've just made that drive a bunch of times and there are so many directions we have not gone yet! Key West is one of our favorite places though....
