The Smithsonian Museums are great!
They have 19 museums and a zoo.
You can visit them all for free.
My favorite is the Air and Space Museum.
You can see things from the Moon landing there.
The Natural History Museum has the Hope Diamond, which is very beautiful.
The American History Museum has the star-spangled banner.
It is very special.
You can learn a lot and have fun.
You should definitely go!
