Classic queer nightlife
Visit Arlington National Cemetery to pay your respects to America's heroes, to include former presidents and servicemembers. Here is where the Tomb of the Unknown Soldier lies. The cemetery is huge, so there is a tour available via a "hop-on hop-off" bus that is internal to the cemetery. You can also walk the cemetery (bring comfortable shoes).
To visit the White House, you must submit a request to one of your senators or congressional representatives, which you can find using the information on the link provided. Then visit the senator/congressional representative's page and search for a section labeled something like "visit Washington, D.C." Tours fill up quick, request a spot early on!
