I know someone posted in the Museum about Sydenham being on the Google Street View, but I just had to point out that if you follow the camera down Sydenham Road, not only do you see the smokers standing outside The Railway, but also the drinkers on the bench outside the Post Office. Superb.
It also changes from brightish daylight, to dusk, when you are near the roundabout outside The Greyhound.
I've heard that should the drinkers ever leave the area outside the Post Office, then Sydenham will be no more; much like the ravens and the Tower of London.
I don't think you can see the street drinkers (although there are a couple of people by the benches), but there are two smokers outside the Railway, one of whom appears to be adjusting his flies.
