I take 8th graders to Washington DC every year. We always go during Spring Break - it is still cold and the Cherry Blossoms are in bloom. The students love the story about receiving the cherry trees from Japan so long ago. There are a lot of opportunities for the students to learn about Asia on the trip. War memorials as well as China town in New York - that is an eye opener! I would really encourage other teachers to do this trip if you can!
