In China, in Europe…in most areas, there are many kinds of transportation options you can choose. In America, not so much!
Consider this: Europe has Eurail, a train system that covers most of the continents, and China has high－speed trains(高速列车)as well as slower trains. In fact, the whole country is full of rails, making it easy to get anywhere. Trains are usually punctual(准时的), safe and efficient.
America has no train system to speak of. Nearly 100 major cities in America, such as Las Vegas and Nashville, have no train service at all. In South Dakota and Wyoming, many lines were given up in the last 30 years because they did not have enough money to keep them running. Some trains only run every 3 days, so if you have to be somewhere at a certain time, you'd have to make your schedule carefully.
Is it comfortable to fly across America? Well, no. If you're hoping for something to eat, you'd better have a credit card(信用卡): all food must be bought, and you cannot pay with cash. "Plane food" is about as expensive as food you would buy at the airport.
But it is very safe when you fly in the USA. You can't bring sweaters or coats on the plane. It takes longer time to get through security than to check in to your flight and get to the gate!
