If you get to the visitors gallery at the CBOT early enough and compose the photo just the right way, it still looks like this manner of trading is vital. Pan right or come back after noon, though, and it’s a different story.
Kinda funny—the observation area is so little used now that they leave the lights off. There is technically a “no photos” policy up there but security is too disinterested to bother. If there were wifi, it’d be the perfect place to escape.
