Is England possibly the dullest place in the world? Could you c/c please?

I'd drop "concrete jungle" it's too cliche. The rhymes are good. Mexico is nice in tourist resorts, but the rest of the country, like the people, are the dirtiest. Then they have the nerve to bring their filth to America, illegally, use our welfare and act like it's their country. England might be full of dark-skinned Muslims and blacks, which is why it looks darker to you.
