Travel by train

I always say that riding on Amtrak is a chance to see the backside of America, but in addition to the littered back alleys of urban areas the train provides the opportunity to see places that are difficult to get to any other way.
The coast of Southern California
Traveling along the Mississippi River for miles, Around the foot of Mt. Shasta, Point Defiance, are just some examples, & the frozen Potomac.
