I'm also interested in historical pub listings, but my interest stops a long way short of a photo of whatever monstrous building now occupies the site. I remember Conrad having a bit of a laugh at my identification of the correct site of this demolished pub. I was pleased to see the pre-demolition photo that was posted on Pubs Galore, but the last thing on my mind was to dash out and take a photo of the patch of grass and the advertising board that now stands there.
Most of my friends and family already think I'm pretty crazy for taking photos of pubs, but taking a photo of a demolition site would be, if I can borrow ROBCamra's word, madness!
