I'm safely back home from Conclave. Generally had a swell time. I went to Mark Bernstein's voice training. I seem to be able to bellow adequately. Now, control is another matter.
I learned Fermi lab can store anti protons for several days if need be.
And I made three 24 inch parachutes for my model rockets. Two were high performance quarter mil aluminized mylar (shiny!) and the third was made of diffraction grating/rainbow (pretty!) plastic.
