Chi-Town, Second City, or The Windy City. Whatever you call Chicago, the city's downtown area has more than enough to keep visitors busy.
Situated on the coast of Illinois, and right next to Lake Michigan, Chicago is the country's third largest city, behind Los Angeles and New York City.
Resident Shelby Walker lives right outside the city, but said she loves commuting in for the day.
"I love hoping on the train," Walker said. "It's $2.25, it takes me a half hour to get downtown. I head straight downtown to Bukingham Fountain to watch the water shoot in the air, and then go see the boats on the lake."
Chicago is home to more than four art schools in the heart of the city and it's no stranger to beautiful art and architecture.
Leslie Ramirez has lived in the city for more than a decade and wonders what's not to love.
"I've been here for 16 years with no intention of going anywhere else," Ramirez said. "I love it. I love the architecture. It's the birthplace of the modern skyscraper."
At night, the theatre distract comes alive with off-Broadway shows and other popular productions. Other notable sites are the Magnificent Mile, the city's largest shopping district, and downtown's Canal Walk which is in an area of the city called the Loop, known for the many kinds of people that live and work there.
"What keeps me in Chicago are the people, the neighborhoods," Ramirez said. "People say Chicago is a city of neighborhoods. You can be in Little Ukraine one day, and Little Poland the next. There's a little slice of Mexico, Puerto Rico, and you know everyone is pretty harmonious."
But there is another kind of resident - The presidential kind. In the center of the city, in the Presidential Building, is the headquarters for Obama for America. When Obama won four years ago, he held his campaign's victory celebration in Grant Park, where an estimated 240,000 had gathered to hear him speak.
This year, Obama will be at McCormick Place, the largest convention center in North America, situated right on the coast of Lake Michigan, about three miles south of downtown Chicago.
