It's the end of May. Yesterday the temperature here in Virginia rose to 36 C / 96 F and today is forecast to be even hotter, with a hazardous weather outlook and an air quality alert.
While sweltering outside yesterday, I was asked about the wool uniforms worn by the Confederate army in the summer during forced marches and battles.
I really don't know how they managed.
I've heard the Berbers in North Africa wear wool in the hot desert. I've heard that sheep get some insulation value during hot summer weather from the wool that grows back after spring shearing.
