How cool is that? I just love stuff like that. I know that some cities have 'sponsored' street art, a guy I follow from Berlin has shown some of it.
I spent last summer in Spokane, Wa. They have had a 'street art' program for at least 25 years. It's an industrial sort of place, and a big rail hub so there are literally hundreds of overpasses. Many have been given over to street art, and it's a cool project.
I'm anxious to see the whole thing. And hear the rest of the story.
Thanks.
