I forgot to mention, in my report, that we spent every night of our Christmas trip stargazing. We had a wonderful view from the studio at Mt. Vernon. Orion started his journey through the sky at about 6pm. We also could see Gemini, big and little dippers, and, I think, Taurus. There's a great ipad app that identifies all the stars and other celestial objects when you point it at the sky--Skyview. It was a wonderful cap to a day of sun worship at Club O.
