While in Washington D.C we spent a day on the" Big Bus" touring the city. You can get off at any number of stops, see the sights, attend a museum, and then come back to the bus stop, hop back on and ride to the next attraction of your choice. A great way to see the sights while saving your feet. In between stops I had to play a little ditty, much to the dismay of my long suffering wife. I just carried the "Pinecone" in my brief case.
