When I last ventured to DC, I took a selfish day before the hearings and visited Gunston Hall, the home of Founder George Mason. Luckily, the Friends of Fairfield Archaeology were having a seminar that Saturday and I learned a heckuva lot about local historical archaeology, Gunston Hall, etc. and met a whole bunch of nice folks. Now, FOFA is having their Spring Symposium on Archaeology of the Civil War at the James Lee Center, Monroe Gymnasium, 2855 Annandale Road, Falls Church, Virginia on Saturday, March 31 between 8:30 AM and 3:30 PM. Admission is free, although seating is limited to 200.
I mention this because one of the topics will be Civil War Crimean Ovens, presented by Wally Owen, Assistant Director of the Fort Ward Museum and Historic Site (which was itself within spitting distance of my hotel).
I have always been interested in military technology and this method of heating large tents and living spaces without endangering the occupants with carbon monoxide poisoning seemed interesting to me. Offered for what it is worth.
