Hi Sasha(или другое имя)!
How are your? I have just come from the USA. It was wonderfull and I want to come back there...
I want to tell you about my trips to the Grand Canyon and the Mississippi River.It was amazing! I like it very much! 
The Grand Canyon is really beautiful place.  It is one of the most wonderfull places in the world! It looks like split mountains. This place is located very high and sometimes it was dreadfully.
The Mississippi River is located in the USA too! It is very long and beautiful river. I had a water trip on this river and I made some photoes for you. I put them in my letter and you will see it. 
I miss you very much! 
See you soon ,
