I've been in research mode here in the Colorado region looking for farms dealing in small grains and made another new discovery, High Desert Seed + Garden out in Montrose, Colorado. While not necessarily a farm that is selling berries, they are growing and selling regionally suited seeds that farmers can buy and grow:

There are not many established markets for finding and buying regional grain to use for our bakery, so I am trying to build out our database so that any food-based companies that end trying to find these grain purveyors like we are at least have a place to start.
