My impressions. Correct, please error!

For several years I lived in Moscow, it is a very, very big city compared to my hometown. Once in the flow of people, you feel like a small sliver in the vortex, the streets are packed, the underground is packed - people, people, people ...And here, you really feel the rhythm of a metropolis!
I often went with friends to theatres, museums, exhibitions and to parks. Most of all I liked to walk in Kolomna park because it is very, very beautiful. From the embankment you can see large ships floating on the river, there are ancient monuments, churches, and lots of greenery. And of course I liked the zoo, especially the aquarium with the dolphins and sea lions. ) 

Moscow - a city of great ideas and opportunities, and good people!

I lived in Moscow for several years, which is a very big city compared to my hometown.  Once you are within the circulation of people, you feel a small sliver in your vortex.  With the streets so filled, as well as being filled with so many underground operations, it's just people, people, people!  From this moment onwards, you really feel the rhythm of a metropolis!
I often went with friends to theaters, museums, exhibitions, and also the park.  Most of all, I loved to walk in the park called Kolomna, because it is very, very beautiful.  There's an embankment by the river for large ships, ancient monuments, churches, and lots of greenery. And, of course, I admired the zoo.  I especially liked the display of the dolphins and sea lions.
