Old Dominion yesterday delivered the official Christmas trees to the Vice President’s residence at the U.S. Naval Observatory in Washington D.C.

Vice President Mike Pence’s wife Karen was on hand to welcome the Old Dominion driver from the Manassas, Va., service center who delivered the trees. The four 12-foot Christmas trees were transported by Old Dominion across the country from the State of Washington for the special delivery.

The Christmas Tree delivery is an annual tradition for the vice president’s home. The trees came from Hedlund Trees in Montesano, Wash., the same farm that produced the official White House Christmas trees for the Clinton and Bush families.

In case you were wondering, the vice president’s official residence is known as Number One Observatory Circle. It is a large home that was built on the northeast grounds of the U.S Naval Observatory in 1893. It originally housed the U.S. Naval Observatory superintendent. until it was later designated for the use of the Chief of Naval Operations.

In 1974, Congress established the home as the vice president’s residence. Walter Mondale was the first vice president to live in the residence with his family. Every vice president since Mondale has lived there.
