Couchsurfing is basically freeloading high-tech style. LOL.  The way it works is that you go to www.couchsurfing.com and register yourself and whether you have a couch for someone to sleep on and when it’s available.  You can also search for people that have couches in parts of the world you plan on visiting.  It’s sort of like a foreign exchange student program for people that wish to travel, host, or both…just without the foreign exchange student.  I’ve known about this site for quite a while but didn’t realize what a hidden gem it was.  There are over 1 million members in 231 countries on this site!  It’s definitely something worth checking out if you are a traveler on a limited budget like moi!
