Make a movie in your mind to remember the capital:
Picture a rich man in Europe sending settlers to start the first colony in Virginia. 
Rich + man = Richmond sending colonists to Virginia.  Richmond, Virginia.

Why is Virginia called the Mother of Presidents?
More US presidents were born in Virginia than in any other state - 8.  They were George Washington, Thomas Jefferson, James Madison, James Monroe, William Henry Harrison, John Tyler, Zachary Taylor, and Woodrow Wilson.

The Natural Bridge, south of Lexington, VA is a 90 foot wide, 215 foot high stone formation that really is a bridge - US Route 11 runs directly over it.  It was once part of a limestone cavern, but millions of years ago the soft rocks that made up the roof of the cavern collapsed.  Some harder rocks were left standing, which formed the bridge.  Over the years, the stream that runs under the bridge carved away the bridge opening.  The first person to own the land surrounding the Natural Bridge was Thomas Jefferson, the third president.  He was fascinated by this geological oddity and asked the royal governor of Virginia to grant him a tract of land that included the bridge in 1774.  For many years he maintained a cabin there.
