New York City

New york City is made up of five boroughs which include Queens, Manhattan, Brooklyn, th Bronx, and StatenIsland. The city is the home of approximately 8 million people.
In 1876, France gifted the Cityof New York what is known as the Statue of Liberty, which is currently located on Liberty Island and commonly visited by tourists.
However, it took 10 years to assemble and therefore wasn't unveiled until 1886.
Another tourist destination is Time Square. Time Square is commonly known for big buildings, Broadway shows, and bright neon signs.
This famous location was named after the The New York Times after the Times moved to that location. Prior to that, it was named Longacre square.
New York City is also known for its bridges that connect the boroughs and allow ease of transportation.

This is the Statue of Liberty, a popular tourist attraction located on Liberty Island.

While the view in the city is beautiful,the sounds are not as lovely.
Below you'll see an example of the view and the sound you'll deal with in NYC on a daily basis.
