The United States of America has many different Christmas traditions and ways that people in celebrate the holiday, because of its multi-cultural nature.
The traditional meal for Western European families is turkey or ham with cranberry sauce. Some Americans use pop-corn threaded on string to help decorate their Christmas tree!
Many Americans, especially Christians will go to Church to celebrate the birth of Jesus at Christmas. Many churches have special Christmas Carol services and events where the story of Christmas is told.
Americans also send out Christmas cards, like Carol singing and there's the unusual custom of the Christmas Pickle!
People in America like to decorate the outsides of their houses with lights and sometimes even statues of Santa Claus, Snowmen and Reindeer. Some cookies and glass of milk are often left out as a snack for Santa on Christmas Eve!
Towns and cities often decorate the streets with lights to celebrate Christmas. Perhaps the most famous Christmas street lights in the USA are at the Rockerfeller Center in New York where there is a huge Christmas Tree with a public ice skating rink in front of it over Christmas and the New Year.
