Having explored the Bronx and Brooklyn, Sigrid now tells us all about Queens, which is geographically speaking the largest of the 5 boroughs of New York City.

Sigrid talks about the different ways to get from Brooklyn to Manhattan, and about some of the characteristics of this borough. For one thing, it is more affordable than Manhattan, although by no means a cheap place to live.

In the first of two parts, we look at Brooklyn's beginnings and how it came to be one of New York City's boroughs.

The borough of the Bronx has gotten a bad name because of issues with poverty and crime. It's also had its share of neglect and mishandling on the part of local and state administrations. However, the Bronx also has some claims to fame, such as the Bronx zoo and botanical garden.

The Bronx was the first area to become part of New York City. Lying to the north and northeast of Manhattan, it was a logical addition. The quirky name of this borough has its own history.

Sigrid seeks to answer the question "What's a borough?" In doing so, she talks about how New York City got its start, and also about the surrounding counties that played an important role in its development. In this video, you'll see 18th- and 19th-century maps of the area.
