There is no reason to cross the U.S. by train, but I did it anyway
Headline like this won't get me to read the article. There's plenty of reason to cross the country by train. You could be afraid of planes. You could just really like trains. You could like to see the country from the ground.
Maybe it's a romantic experience or journey. Who knows, but there are certainly really good reasons travel across the country the way you want to.
