(Editor’s Note: This is the third in an ongoing series on the D.C. area’s overlooked museums. Here are Parts I and II.)

Nothing to do this weekend? Stuck in town while your friends go to the beach? Make them wish they had been around and gone with you to one of these sleeper museums. You’re sure to have a story to tell. And if you don’t, make one up.

Kick Memorial Day Weekend off right with a visit to the National Firearms Museum in Fairfax. Remember those who died in service to this great nation with a look at the weapons that killed them. Located in the National Rifle Association’s headquarters, the museums collection consists of more than 3,500 historic and modern firearms, the museum is. See the revolver awarded to Gen. George Gordon Meade for his victory at Gettysburg and a rifle belonging to gun-toting Annie Oakley. If you check out the museum’s website, you’ll see information about the Gun of the Month, a Winchester Model 70 bolt-action rifle with a built-in radio. Now, DCist isn’t that into guns but this one has some merits. Think of the possibilities! You could go out shooting in the early morning and not miss “Morning Edition.”

The O. Orkin Insect Zoo inside the National Museum of Natural History is the perfect first date, no? Not only can you see live spiders, centipedes, millipedes, and insects year-round, you can also get ideas for dinner with a display of crabs, shrimp and lobsters. Apparently those tasty morsels are arthropods, or insects by association. Discover how insects infiltrate your life. Insect ecosystems are everywhere—from moths in the clothes to cockroaches in the kitchen and beetles in the flour. Still feel like eating a lobster?

Did you know we had a Radio and Television Museum? Did you know it was in Bowie? Are you unsure where Bowie is? If you find out, you can explore radios from Marconi’s earliest wireless telegraph to the crystal sets of the 1920s, Depression-era cathedrals, and post-War portable radios. See how those paved the way for radio with pictures, aka television.
