Yesterday I went and demonstrated at the Durham Museum in Omaha, this is actually the old Union Station. The event was actually called Wild West Days and was Old West themed.
What I thought some might like it the way they had me set up, see the big problem is where I demonstrate is actually on top of a parking garage near the main entrances to the building, not really a place I can build my normal fire.
The maintnace guy called me the other days and told me his idea, it was better than the one last year because they can just move it and store it since it's on a pallet, when it cooled down they were going to put it on the frieght elavator and put it in storage with the other stuff they had and can just leave the dand in it. They built the box on a pallet and put cement board down under the sand to keep the heat away from the pallet, then my fire was built out of lump charcoal.
What we ended up was similar to what I've seen desribed being used on ships on deck in calm weather, I thought maybe this would be useful for someone who wants to set up where any type of normal fire is out of the question. I did have to use one of my trivets to help keep the legs from sinking, but it did work out well.
All I cooked was plain out white bread and then gave out samples, I was one of the most popular displays there, I had bread baking and almost ready to come out at 10 am when they opened and kept one oven baking, and one rising till after 2 pm when the crowd thinned (it was open to 3 pm.)
All in all, people love homemade bread warm right out of the oven, someone making butter would have been nice, but people just gobbled it up plain anyway. It went well, a lot of people had never seen dutch oven cooking done and some had never heard of it and had no idea what could be done in a primative situation.
(The trivet picture is from another day when it was used on top of an oven for a sauce pan or coffee pot, I can't remember at this time.)
The other guy in the picture with me is a Pullman Conductor.
