If you're in Chicago with all your camera equipment…
…And you can get a hotel room across the street from the Historic Chicago Theater… on the 7th floor… above the 'L' tracks… and you've talked the theater owner into turning on the marquee lights even without a show… and nobody parks a truck in front… and it isn't raining or snowing… and the sun is setting… and the 'L' train comes into the station… and you've got plenty of film for your Hasselblad… then it's easy.
