Some boys and girls travel in Russian and abroad with their parents. russia is a very big country, bigger than many countries in the world. There are a lot of interesting placec in it. Last summermy parents and i travelled to Nizhny Novgorod. Nizhny Novgorod is an old city on the Volga. My sister Kate, ourparents andi went to Nizhny Novgorod by train . To travel by train can beas comfortable as to travel by plane or by sea. We liked the city of Nizhny Novgorod , one of the biggest and oldest cities in russian. we saw the Kremlin with its thirteen towers and went to Pokrovskaya Street to buy some presents for our friends.
