After touring the historic Washington monuments display and the NPS tribute, we (or more correctly, I) decided to also see the model train exhibit, which in reality was a series of re-creations of iconic national parks and sites in the National Register of Historic Places, all made from plants and other natural materials, with some model trains running through them. Unfortunately, it was packed, and we had to wait for almost an hour outside in the cold and then snake our way in line though the conservatory to get to the entrance of the exhibit.
While making our way to the exhibit, we passed this moose.
