The Liberty Theatre and the Camas Farmer’s Market will offer a special showing of “Common Ground” at 11:30 a.m. April 20 and 7 p.m. April 24. The documentary is the sequel to “Kiss the Ground,” which inspired the United States Department of Agriculture to put $20 billion toward soil health. With personal stories from those on the front lines of the food movement, “Common Ground” unveils the web of money, power, and politics behind the food system. Tickets are $10 and ten percent of all proceeds will be donated to the Camas Farmers Market.
