The open is a triple with the line set up on a hill and all three gun stations set in the flat below. Order in long middle, short left, then long right flyer. Both left and middle guns retire: middle guns retire by moving to flyer station when dog has picked up flyer and is returning; left gun retires (as I recall, specific instructions may be different) after dog passes en route to flyer...some (either dog or handler) have primary selected on the short left gun. There is a strong crosswind from left to right. Handler shown in the picture is the honor position...the running dog is positioned to their left. Saw dogs go both left and right of the cedar tree in the middle on their way to the long retired but the ones I watched swam around the point and down to the end of the pond, driving left (bad) or right (good-downwind) of the bird. Obviously, there is a lot of varied work on the test.
