St. Gery's clubs and bars are packed year-round. Seafood eateries abound in Ste. Catherine. Walk, rather than get snarled up in traffic, in the narrow streets.

Holland's most modern city began as a fishing village in the 13th century. It was developing into an industrial and trading power when German bombers destroyed the city center and harbor in 1940. However, Rotterdam's unique architecture now brings many visitors to bike around this urbane, cosmopolitan city. Old Dutch-style houses can still be found in historic Delfshaven, from where the pilgrims set sail in 1620. Cultural offerings from summer's carnival to classical music give Amsterdam competition.

Atlanta has been dubbed everything from the "capital of the new South" and "the next international city" to "the best place to do business." It's also a great place to visit.

And this time it's a good thing. From world-class restaurants and a myriad of cultural attractions to a hip nightlife and sporting events galore, the city is cosmopolitan in every sense of the word. But Atlanta has also managed to maintain its historic character. Stop by the Atlanta History Center or visit the Martin Luther King Jr. Historical Site, a moving tribute to an American icon.
