First of all we are going to do a lot of sightseeing. We are going to see the Kremlin, Red Square, St Basil's Church, Lenin's Tomb, the Pushkin Museum of Fine Arts and The State History Museum. Dad is also going to take us to the famous Bolshoi Ballet theatre. Isn't it wonderful, My sister wants to go on a day trip down the Moskva River but Dad says it's too tiring, so we are not going to travel there. That's OK though because we are going to spend a whole day at the Moscow Zoo, the largest zoo in RUSSIA which has a great collection of animals and exotic species.
I'm going to take lots of interesting pictures to show you when I get back. I'm also going to bring you a Matryoshka.
