Zacatecas, built into the slopes of a narrow ravine in north-central Mexico, is a city with a deep mining past and a striking skyline. The historic center, a UNESCO World Heritage Site, is known for its pink cantera stone buildings, narrow alleys, and impressive baroque facades. The Cathedral Basilica of Zacatecas, completed in 1752, stands as one of the most detailed examples of Mexican baroque architecture, with hundreds of carved figures covering its sandstone exterior.

Virginia is a state where past and present share the same ground. In places like Colonial Williamsburg, costumed interpreters walk the same streets once frequented by American revolutionaries, while nearby Jamestown and Yorktown complete what's known as the Historic Triangle. Outside its historic corridors, Virginia surprises visitors with its changing landscapes, from the rolling horse farms of Middleburg to the rugged terrain of the Blue Ridge Mountains.

Theodore Roosevelt National Park, tucked into the rugged badlands of western North Dakota is where a young Theodore Roosevelt came to recover after the loss of his wife and mother in the same day.

Visitors can still see Roosevelt’s original Maltese Cross Cabin near the park's entrance and walk trails he once rode on horseback.
