I know this is in the middle of a game, but can we adopt the sort of rule that the item has to be clearly seen, as there has been a couple of instances recently where things have been a bit difficult. For instance
I know there are ten bridges, 100,000 cars, 15,000 bikes, a million lamp posts and trees, hundres of warehouses, assorted litter bins, life belts. lakes, ponds and canals, and yes skyscrapers. But as all but the sky scrapers a tree or two and possible 'a city from afar' can be identified, ther's not a lot more can be used for the game. What to people think?
