That was the sun yesterday afternoon. When I went to lunch everything was normal, sunny with some clouds. At about four o'clock I took a break and everything was sepia. I thought I walked outside into a Clint Eastwood western.
The dust swept in like a thick fog. That is the only way I can think of describing it. My eyes didn't dry out, nor did I sneeze. You couldn't touch it or feel it, but you could see it.
I wasn't the "wall of dust" I wanted to see, but close enough.
