Different Tastes For Vacation
People like different kinds of vacations. Some go outside. Others like to stay at a hotel in an exciting city. They go shopping all day and go dancing all night. Or maybe they go sightseeing to places such as Disneyland, the Tai Mahan or the Louver.
Some people are bored with sightseeing trips. They don’t want to be "tourists". They want to have an adventure, to learn something and maybe help people too. How can they do this Some travel companies and environmental groups are planning special adventures. Sometimes these trips are difficult and full of hardships, but they’re a lot of fun. One organization, Earth Watch, sends small groups of volunteers to different parts of the world. Some volunteers spend two weeks and study the environment. Others work with animals. Others learn about people of the past.
