The MTR is the best subway I have ever been on. It is relatively cheap, well marked and very clean. You can travel from one end of Hong Kong to the other in just minutes. The stops are all clearly stated in advance, so you can know if it's time to get off the train or not. Very unlike Boston, where unless you are from that city, you cannot understand a word the conductor says! One stop you can be at the horse race track. Just a few seconds later you'll be buried in a mass of electronics stores or just steps away from an old monastery. Another great thing is the cellular antennas inside the train passages. No matter what it might look like on the outside, this is a very modern city. And they can't live without their mobile phones. The MTR is the best way to get around the city and even to and from the airport. One thing to remember about Hong Kong that is very important, if you need to travel from one side of the harbor to the other, this is about the only way, short of the Star Ferry. Good luck getting a cabbie to go across without charging you a small fortune.
