Last year, I went to the United States of America with my mom and friends. We went there for seven days. We went to New York, Philadelphia, Williamsburg, and Washington D.C. We got there by airplane. It was really a long trip and we rode an airplane for 17 hours. At the first day, we went to New York. First, we visited the Ocean World. It is the biggest Ocean World I have ever seen. The second day we saw the tallest tower in America. I thought it was taller then 200 giraffes. Then we went to Washington D.C. The streets were so clean that I didn’t want to walk on the street. During the remaining days, we stayed in Philadelphia and Williamsburg. I enjoyed these two cities. What a wonderful trip it was!
