After getting my Linhof Technika III up and running, I was anxious to get ahold of some 4x5 sheet film to try it out.  Luckily, my good old buddy Adam (check him and his work out at http://www.contentunknown.com) had an old, and mostly full, box of Arista sheet film.  Adam claimed that this film was left in a desk drawer inside a sweltering warehouse for a couple of summers.  Then lived in the back of his truck for quite sometime.  "Use it at your own risk," he warned.
