Any time you're in unimproved areas you'll see dust, dirt and sometimes mud. Imperial is no different. To minimize it pick a location that is away from traffic, is upwind from any traffic, and is in the more graveled areas rather than dirt or dust. We try to spend a week or two at Imperial and another week at Quartzsite. definitely dirty, but a fun place for us.
