The website couchsurfing-dot-com is a social network in real life. Ten years ago the non-profit began by connecting young travelers to couches in cities around the world. Now, for some, the couchsurfing community has become a way of life. More than 2 million members in 245 countries  don't just crash on couches, they help organize events for fellow travelers that serve as a kind-of cultural and creative blender. Last fall, two long time couchsurfers - who count themselves among the site's first 10,000 or so members - began an emerging collaborative tradition called "Album in a Day." The concept of gathering a group of strangers to record an album in a day is now carrying itself to the far corners of the Earth through its well-traveled participants. Toby Scott visits innovators Josh Sarro and Greg Hardy in the Wallingford neighborhood of Seattle as the two globetrotters again connect friends and strangers to produce another album in a day.
