Going to DC this weekend and visiting the White House. Does anyone know of any special perks in DC for being military?

Sorry, no special perks on the WH tour.

No. However, you really don't need any perks since the Museums and Monuments are all free.

No,but you can go see Arlington.

You have WH Invitation? Jeremy Bernard WH Social Secretary is particularly helpful . . .
Otherwise much to do in Washington DC . . . for free, small donation, or inexpensive . . .
If this if your first time . . . grab a AAA or other travel guide book from the bookstore . . .
For me . . . Arlington, Lincoln Memorial, The Wall, Smithsonian, Aerospace Museum . . .
Google is your friend . . . as are Priceline and other travel, hotel, and car rental sites . .
