We recently visited DC. I've never been, so it was all new to me. One of my favorite spots from the trip was the Reptile Discovery Center at the Smithsonian National Zoo. I especially loved all the different carvings on the outside of the building. The turtle holding up the post is my favorite. Simply because I know that some cultures believe that a turtle holds up the world. Just strikes me as a cool idea. In general, I love the detail on these carvings. To me it makes for very interesting architecture.
