Awesome picture...I LOVE Google Earth. It's like being Superman, flying over the country and the world.
I didn't realize just how large the south lawn is.
I love Google Earth also. It's great fun to "fly" anyplace in the world you want to go. That image shows the entire WH complex. The Old Executive Office Building which houses the ceremonial vice presidential office is on the left (west).
A lot of people think the Oval Office is in the White House proper -- the famous building we all think of when we think "White House." But it's not. The main building is the Residence. The Oval Office is in the West Wing and can be spotted in that image. Just look for the oval shape. The Rose Garden is the small lawn area just to the right of the Oval Office.
