Rising from the ruins of the Aztec capital, Tenochtitlan, Mexico City offers a unique collision of contemporary city life and historic preservation. World-class museums, restaurants and parks rub shoulders with the remains of several cultures. The nightlife, the shopping and the history make it a must-see regardless of your travel style.

Located on the shores of Lake Michigan, Milwaukee is perhaps best known for its famous breweries and the Major League Brewers, but there's more to the city than beer and baseball. Milwaukee is rich in historical and cultural attractions, making it the perfect place for a weekend of exploring. Visit the newly expanded Milwaukee Art Museum or the Mitchell Park Horticultural Society, which hosts an annual show of the same flora and fauna seen in Georgia O'Keefe's paintings. Those interested in the city's history can visit the grand Pabst Mansion, former home of one of the city's famous beer barons, or the Milwaukee Public Museum, to see what life was like in Old Milwaukee. If you have children with you, don't miss the Milwaukee County Zoo or the Betty Brinn Children's Museum. Of course, a trip to the "Genuine American City" would not be complete without a tour of the Miller Brewing Company and a Brewers game at Miller Park.

Although the once glittering Last Chance Creek has long dried up, Helena's Gold Rush history is reflected in its preserved architecture, from the spires of St. Helena Cathedral and the Queen Anne style Original Governor's Mansion to the restored miner's village of Reeder's Alley and the oldest house in the city, Pioneer Cabin. For those seeking adventure, the paths of Mount Helena Park provide ample activity. Helena also offers much in the way of arts and culture with theaters and galleries.

Everyone who visits Paris for the first time probably has the same punchlist of major attractions to hit: The Louvre, Notre Dame, The Eiffel Tower, etc. Just make sure you leave some time to wander the city’s grand boulevards and eat in as many cafes, bistros and brasseries as possible. And don’t forget the shopping—whether your tastes run to Louis Vuitton or Les Puces (the flea market), you can find it here.
