Mo's right, the dust there isn't substantial at all. In the images you took, dust would be easily visible on everything after only a couple of days here. I have the luxury of an air compressor, and I tend to use it often enough. Regular hardware cleaning is a must for me. That includes my speakers keyboard and mice, believe it or not. Though I always leave my monitors alone, they do alright. Tends to happen when you live off a dirt road and the trees have yet to grow in to block the dust. People have this goddamn problem with going 70 miles down the dirt road... consequently killing any living thing on the road and sending dust clouds everywhere. Asshats.
