I think they just do it on purpose to annoy us 'proper' climbers...
...a couple of years back I spotted this huge poster in Sheffield. It was displayed in the window of some city-centre premises being renovated at the time ('Henry's', for those interested...):

The poster featured photos of several recognizable Sheffield/Peak locations, but the climbing pic wasn't one of them. The rock was obviously Granite, but beyond that, I had no idea.
By a stroke of luck, whilst working on a personal project last winter, I discovered the full details. Answers on a postcard please...
Pete.
