Travelling has become an important part of our life. People travel not only on holidays but on business as well. Some people travel to other countries to get education.People travel for different reasons. Some people travel to relax, to have a rest after a trying working year. Some people travel on business, to negotiate with their foreign counterparts or settle a deal. Some people travel in order to learn something new, they strive for new emotions and impressions.Undoubtedly, traveling is a pleasant and useful experience. It broadens people’s mind, allows looking at current problems from a different angle and finding a better way-out from some difficult situation.People choose different ways of traveling. But planes, trains, buses and cars enjoy the popularity among people the most. Planes are popular among business people who try to save their time as they carry passengers quite fast. Buses are suitable for travelers who want to enjoy the views of the country or city. They may be uncomfortable if the trip is too lengthy. Trains are the most popular means of transport among travelers as it is cheap and gives a possibility to rest on a berth.Whatever country or city you choose, whatever way of traveling you choose the thing about traveling is your feelings, emotions, aims. This what makes the trip unforgettable and memorable.
