I've never been to San Fransisco, California ... although I've seen enough pictures to feel like I have.  But I recently came across this guy's website named, Adam's Block and I am completely mesmerized by it.  I had never heard of The Tenderloin section of San Fransisco prior to seeing this website but I am totally addicted now!!   Basically this guy has live streaming video of his neighborhood going 24 x 7 and has also archived video of the more "colorful" events that have gone down on camera
