 families, camping is a popular vacation activity. Camping is less expensive and more adventurous (冒险

  countries.  A family can set up a tent or park their campers at one of many campsites.

     Another kind of vacation is a road trip. A road trip is where families pack up their cars and hit the road.

  Many families will visit relatives or friends in other parts of the country or enjoy another city. It usually

  takes several days to reach the destination (目的地).Families take their time, stopping for picnics.

    There are also many summer camps, especially for children. The camps can last from a week up to

 three months. Some camps are educational such as music camp or computer camp. However, most of

 them are just for fun.  Campers spend a lot of time outdoors enjoying activities such as swimming, hiking

  and doing arts and crafts together. They stay in cabins and eat together in a big building. Most camps

  have a campfire at night. Everyone gathers around a small fire to sing songs and listen to stories.
