Check out this great collection of images by jim and karla murray. The images in the Flickr set: The Disappearing Face of New York City Storefronts will be featured in their upcoming new book, "Counter/Culture: The Disappearing Face of New York City's Storefronts" coming out at the end of this year. Interestingly enough they also have a nice set of decaying Miami images here.
Below is a picture from that set in one of the many Hialeah, FL abandoned warehouses turned into street art gallery and shelter.
