GWUK

The Guess Where UK pool on Flickr is one of the treasures of the interweb. A year ago I could even win the occasional point by recognising somewhere before anyone else, but I was never close to being in the same league as the real experts, and these days I am in awe of the standard of detection.

The regulars have excelled themselves for April Fool's day though. It's worth another look if you haven't dropped in for a while.
