It is unlike any chair I know. It scares the heck out of me every time I ride it Intimately high. I'm talking of course about lovely chair 23. I love to ski at Mammoth Mountain California. One of my favorite chair lift is chair 23. It serves the hardest train on the mountain. It has awesome runs off it. Chair 23 goes over really sharp rocks. plus it doesn't help that it was installed in the 1980's. Scary.
