You know what this is actually a fantastic idea, we should get this thread stickyed. It's gonna take some time to get those pics but bare with me. I have had a few idea's just reading the list. I am in London man, this is a great excuse to go exploring.
Examples -
GT'ers name - I saw a shop the other day called Camp-Fu
Statue - I saw a statue of Abraham Lincoln the other day, some of you guys may appreciate that.
Legend - I will have to get a picture of the Winston Churchill statue I saw.
Tallest building - Canary wharf, BT tower, London eye.
