Correct me if I'm wrong, but based on pictures I've seen, could the Grizzly have once been a clone of SFGAm's American Eagle. I'm inclined to beleive this because PGA and SFGAm were originaly twin park owned by Marriott corporation. The station, turn around leading to lift, and the lift itself look very much like the station, turn around leading to lift, and the lift itself on American Eagle's red side.
