Monday, May 25: The Smithsonian is Open on Memorial Day!
That's right—the Smithsonian museums are open on Memorial Day! Come enjoy the sights that make the National Mall such an awesome tourist destination. I heartily encourage you to make a point of visiting the war memorials, from the all-but-forgotten WWI memorial to the Vietnam War memorial. No, they're not part of the Smithsonian (the memorials are National Parks territory) but one ought to take a few moments to think about all the men and women who have served this country. While the Smithsonian doesn't have any special Memorial Day-themed events happening today, go to goSmithsonian to get the lowdown on all the museums and plan your day.
