Unknowingly yes! lol
Last August my daughter and I took off for a week in the Redwoods in Northern Ca.
Picked up a couple of Couchsurfers on the highway and dropped them at their hosts house in Eureka.
Had a blast with them!
Awesome young couple, she was from Indiana and he was from somewhere in Europe ( forgot )
We toured some of the big trees and then had a million laughs on the way to meet their host.
I would like to hostess some CouchSurfers, but, have not gotten around to really doing it yet.
I traveled in Asia last spring, but was with friends that already had longterm accomodations.
I think CouchSurfers is a great way to assist and get to know fellow travelers! :-)
