What do spy codes, a Setauket officer’s saber, cherry blossoms, pandas and a postal museum have in common?

This past weekend my family, including eight grandchildren, traveled to Washington, D.C. to visit our nation’s capital together and discover new things. The trip began with a visit to the National Cryptologic Museum about 30 minutes north of Washington.

Here, the story of the secret world of intelligence is detailed with interactive displays and cipher technology from the 16th century to today. One section details the activity of spies during the Revolutionary War, especially General Washington’s Culper Spy Ring, and allows visitors, especially children, to “Create Your Own Secret Cipher,” “Hidden Message,” “Invisible Ink Secrets” and “Make a Secret Code with a Dictionary.”

There is also a “CrypoKids Challenge,” with messages to decode throughout the museum. There is, of course, much more to see here, including captured German and Japanese code machines.

The recently renovated Smithsonian National History Museum along the National Mall includes the exhibit “The Price of Freedom: Americans at War.”

Covering the period from the French and Indian War to the present, “exploring ways in which wars have been defining episodes in American history,” the exhibit includes a stunning array of artifacts, including a dragoon saber belonging to our own Major Benjamin Tallmadge, General Washington’s chief of intelligence and son of the Setauket Presbyterian Church minister.

A late spring provided an April 11 blooming for the cherry trees around the Tidal Basin at the Jefferson Memorial. More than one million people attended the cherry blossom festival in Washington, D.C., however we all went to the National Zoo to watch the pandas play and eat bamboo. A great choice considering the crowds and we did get wonderful pictures of the blossoms the day before.

We spent one morning at the National Postal Museum across the street from Union Station. This may be the best museum in D.C.; it is definitely the most interactive Smithsonian museum.

Visitors can sort mail in a postal train car, ride in a postal truck, select routes to deliver mail across the country and follow a new mail route from New York City to Boston in the 17th century, which became the Boston Post Road decades later. Other activities include letters written home during the many wars and conflicts of the past three centuries and the opportunity to follow these letters as they travel from place to place.

In one simulation of a post office, people come up to the postal window and interact with the clerk. One young girl came up to the window and asked that the Christmas list she was carrying be sent to Santa at the South Pole.

The clerk responded that Santa was actually at the North Pole. The young girl said, “Oh, that’s all right, this is my brother’s list.”

There are many other wonderful stories in the postal museum, including poignant letters written home during the Civil War. There are also real stories about mail fraud, letter bombs and how the security system of the United States Post Office Department dealt with crime.

And not to ignore the Hollywood approach, there are stories about all the movies made about every postal subject from the Pony Express to prohibition.

All in all, it was an experience for visitors of all ages.

In four days, we also visited the Natural History Museum, the Air and Space Museum, and walked around the Washington monument and Lincoln Memorial. All the Smithsonian museums belong to all Americans and admission is free.
