Hi, my name is Mike. I live in SF with my lovely wife and my dog Huck. I just recently re-located my blog from blogger to WordPress.
Flickr user yorkie has started a new Flickr group called The Great Postcard Hunt. Go here to find a challenge postcard (currently the pool includes postcards from Sacramento and San Francisco). Find the postcard location, take a photo of the current location, merge it with the postcard image, and post it to the pool. Click here for the GPH blog.
