Washington State here. We had an unusual build go up near by. Had huge ventilation and filter systems on the buildings. I asked my buddy, who knows everything and talks to everybody. He said he heard, it's "the devil's lettuce" grow operation. I shrugged and thought that was interesting. Then about a year later, talking to the local barista and mention something about those funny looking buildings and she said it was a raspberry plant and cloning operation. They filter all the air coming in and the workers change out of their street cloths and everything, pretty sterile.
