For 625 days, Joshua Langlais forced himself to meet a stranger. He'd introduce himself, and, usually after a little chit-chat, ask to take their portrait. Most of these exchanges happened around Denver. And it had to happen every day .... regardless of the weather or his mood or his schedule. The photos and a description of the encounter are on a web site, http://www.iheartstrangers.com/. Ryan Warner caught up with Langlais to asked him why he started.
