Tried to match up with the exact window mullion, but I think I'm off by one or two- but enjoy the view anyway. As you can see, the skyline has grown susbstantially during the past decades. The Bay bridge is still there if you look hard enough. The mullion is blocking the same building in both the before and after shot. The hills in the background haven't changed a bit. Again, after shot would look better on a sunny day.
A special thanks to the San Francisco Hilton for allowing me up there to begin with. The area was closed to the public for a private event. I told the concierge about my mission to photograph all the What's Up, Doc? locations and he allowed me access to the top floor- with security of course. I think the area is typically closed to the public- the security had to key into the elevator panel to get me up there.
