Hi- I posted about this on the Evanston Farmer's Market section, but for those people that did not read it, the American Conservation Film Festival is ending today 3/28. One of the films they are showing is Seasons of Change on Henry's Farm, which is a documentary about Henry Brockman. They have 18 full length films and many short films. You have to sign up on their site to see the films. The films are free though. Once you select a film to watch you have four days to start watching it. Here is a link to their schedule.
