North and Central America are a traveler's gold mine, virtually limitless in possibilities. In the tropics, one can snorkel and dive in cerulean waters; go spelunking; admire Mayan, Incan, Aztec, and colonial treasures; savor the isolation of a rain forest. In Canada, Alaska and the Arctic, one can walk with polar bears; thrill to the sight of orcas surfacing; try some of the best fishing anywhere. Cities such as New York, Vancouver, San Francisco, Chicago, Montreal, Mexico City, and Los Angeles rank among the world's top cosmopolitan destinations.

We know and love them all.
