Hi, my dear bro!
How nice to see letter from you! You really want to travel in Moscow? I have many great ideas for you)
Firstly, you must try the most popular tradition - visit Red Square. I think that you have this item in your list, but I just must advice you  this amazing place. So many monuments and, for bonus, bro, you can take many pretty photos. Send me several
Secondly, just walk in capital. When I arrived there, I was really surprised. Big houses, crowds of people. Be ready to this because your town versus Moscow is a little cute village
And, the last, - visited Ostankinskya TV Tower. It's the really breathtaking building and excursions there aren't boring. Great surprise, isn't it?
Tell about your trip in your next letter, with photos, please
Good luck on the road
Your best friend, *напиши свое имя*
