how best to describe it…  Its like facebook searchable by region with an endgame of potentially allowing you to spend time at a complete strangers house anywhere in the world.  After using it across the United States and now in Mexico, I cannot tell you how stoked I am that it exists.  Even if I was a zillionaire with money to burn, I wold still use couchsurfing as the cast of characters it has added to the movie of my life is indispensable.  They are all truly wonderful and I have learned so very much!  I can only recommend this fully and wholeheartedly.
