Truly amazing truly amazing... I have boarded 9 trips and this is still the highlight of my trip:
1. The horseshoe curve is the largest in the world
2. Nine tunnels the most in the shortest stretch of track record
And now the best part... leave your seat and go downstairs and stand at the door window...the sensation of riding a surf board... flying.... skiing... you are the edge of the massive canyon.. looking for deer coyote fox and eventually higher than the hunting raptors and if in spring flowers in your face
