Taken from a home video from about 13 years ago. The ride winds through some of the most beautiful country in the US, making several wilderness stops along the way. The weather changes quite a few times along the way, going from sunny and clear to misty and a bit chilly. The river that runs alongside the rails along the way has an odd green tint in places, and there are a lot of small rapids scattered along the way.
