Avenida Paulista and business, São Paulo

Favorite thing: I used to walk a lot along this avenue. There are museums, restaurants, shopping malls, movie theaters, subway stations, and even a small park along its way between high buildings.

Fondest memory: Having an ice-cream next to Parque Trianon on a Sunday afternoon.

Favorite thing: The City great expansion began in the 20th century with the industrialization, which brought even more immigrants like Arabs and Jews. Today São Paulo is the largest city in South America and one of the largest in the world and like other large metropolitan areas has its share of traffic jams, pollution, poverty and noise.

The city has some 16 million inhabitants, 3 million cars and 300 000 trucks and buses. In heavily industrialized São Paulo, the average particulate level is 82 micrograms per cubic meter. For comparison, the annual average PM-10 in the largest 50 U.S. metropolitan areas ranges between 30 and 60 micrograms per cubic meter. Researchers found that when particulates in Sao Paulo increased by 100 micrograms per cubic meter, the overall death rate increased by about 13%.

Favorite thing: Find a tall building where you can get roof access and take in the view of this sprawling city. It is massive!

Fondest memory: I love the diversity of the city's people and the culture. There is so much to experience and to see that one trip won't do. You have to visit Sao Paulo many times to appreciate all it has to offer.

Favorite thing: visit the Centro. It's a bit rundown and littered with street hawkers, but here you can see Sao Paolo's magnificent old skyscrapers. A starting point is the Parque Anhangabau.

Fondest memory: On top of the tallest building in Sao Paolo, the Edificio Italia. Up there, there's a posh restaurant and you can savour the awesome view. I saw a sea of skyscrapers like stalagmites as far as the horizon. It's best at dusk, when the twinkling city lights slowly appear.

Favorite thing: Take a walk along Avenida Paulista. At one time this was THE street live on. Now it is THE street to locate your corporate offices. There are many cafes along the street and an upscale shopping mall at one end an art museum around the middle and a movie theater at the other end. Its not a very long street, but it is one that Paulistanos are very proud of. Spend a day and explore the side streets for a couple of blocks on either side and you will rewarded with interesting food and drink and some nice shops. Be warned things are a little more expensive in this part of town.

Fondest memory: My family. Many of my cousins live in the city. When I visit we hang out, toma cafesinho, shoot the breeze and walk around town.

Favorite thing: Even in very hot weather they wear boots,no idea why

Fondest memory: Fondest memory has to wait a little more too many nice memories here hard to choose one.

Favorite thing: This is just one of them

Favorite thing: A mega city but still works-in-progress! Pretty dynamic! Think about the number of people in civil service!
