We got tickets to the Washington Monument - it was awesome - you take an elevator all the way to the TOP! Then you look out all around Washington D.C. (there is nothing taller than the Washington Monument). It was beautiful - we even saw the Washington Temple far off in the distance.
Next on the agenda - Lincoln Memorial, Korean War Memorial, and the Vietnam Memorial.
After all those memorials we thought we'd have time to see the Air & Space museum (which we did) and we also saw an IMAX movie of the Hubble Telescope. (some of us slept through it - not to mention any names).
