High-Speed Trains in the US?

demondawn asks: "Countries around the world are researching and adopting high-speed rail systems, but the U.S. seems to be behind the bandwagon. How do Americans feel about the adoption of a high-speed rail system in the U.S.? How do people in nations that have already adopted high-speed rail feel about their services? And how about tourists who have travelled either to or from the U.S. feel about public transportation around the world?"
