Ah, couchsurfing. It truly was a paradise and a fantastic community. I have a lot of fond memories when I would just hitchhike whole summer throughout europe and beyond. Meeting all sort of people with every background imaginable. I don't think there is a way for me to recreate that kind of freedom anymore. And the community was really trusting to the point of ridiculousness - I remember one host in Italy had some emergency and had to go out of town for a day while I was about to appear and he just texted me where he left the keys lol
