Got caught in a bad one today. Sandstorm hit just past midday. No warning, just a wall of wind and dust. Visibility dropped to nothing in seconds. I wrapped up as tight as I could, but it didn't matter. The sand found every gap. My eyes are in bad shape. Feels like there's grit still grinding under the lids. They're so red, swollen—I can barely keep them open now. No more moving tonight. I need to wait for the wind to die and figure out if I can even see the next landmark.
