I have nothing but admiration for anyone that takes photographs in big cities.
I went to Liverpool for a day the other week and hated it, I didn't even get the camera out of my bag!!!.
Going through all the outskirts leading into the city center looked so dirty and run down it just totally depressed me. By the time we got to the city center I though "right, I've seen Liverpool and its a $h!thole can we go home now!!!" . I felt exactly the same going through Leeds and London and now I'm absolutely convinced I hate big Cities. Give me the countryside every time.
