My Girl and I had a wonderful day with an old girl-friend of hers, from high school, and her husband and two daughters (youngest autistic) at the National Zoo. The zoo itself is below mediocre and the day was very hot and very muggy, but we really enjoyed the company and the kids.
On Sunday, we went to the National Archives because we're geeks and we just had to see the originals of the Declaration of Independence, the Constitution, and the Bill of Rights. Frankly, it was very cool. I was surprised at how faded the Declaration was and how still readable the Constitution was. At one point, we were reading aloud the Full Faith and Credit Clause and debating its application to DOMA when a guard asked us if we were professors. No, we said, attorneys. He then asked if we were sisters. He was completely nonplussed when I replied that we were wives (my Girl says I should have said "spouses". Mea Culpa).
Before getting there, though, we happened to walk by the Navy Memorial. I'd never really seen it before. It is really cool, with 
really awesome sculptures surrounding a map of the world, showing all the oceans. My Girl took my picture next to the one of the Submarine Service. Then, we realized that I had left her reading glasses (needed, as we were headed to the Archives!) in the car. So, we had to walk 
back. We went via a different route and, consequently, happened upon the WWII submarine memorial, also which I had never seen (indeed, didn't even know existed). A serendipitous find!
