Photos by Taryn Simon of hidden and unfamiliar places in the US, like the marijuana crop grow room at the National Center for Natural Products Research in Mississippi. Here's a somewhat overlapping selection of photos at Wired and another at The Morning News, which includes a great letter from Disney denying Simon access to their theme park's underbelly.
After giving your request serious consideration, even though it is against company policy to consider such a request, it is with regret that I inform you that we are not willing to grant the permission you seek...As you are aware, our Disney characters, parks and other valuable properties have become beloved by young and old alike, and with this comes a tremendous responsibility to protect their use and the protection we currently enjoy. Should we lapse in our vigilance, we run the risk of losing this protection and the Disney characters as we know and love them...Especially during these violent times, I personally believe that the magical spell cast on guests who visit our theme parks is particularly important to protect and helps to provide them with an important fantasy they can escape to.
