American Autocross: In the United States, autocross events are usually held in large paved areas like parking lots or airfields.  Typically, new courses are created for each event so drivers must learn a new course each time they compete.  Courses are designated by a series of traffic cones set out to create "turns" drivers must navigate.  Prior to driving, each competitor walks the course, takes mental notes and develops a strategy to be refined upon subsequent runs.  National organizations such as the Sports Car Club of America (SCCA) and National Auto Sport Association (NASA) sponsor autocross events throughout the United States, and many areas have independent autocross clubs.  Automobile manufacturers and their associated clubs (e.g. the BMW Car Club of America) sometimes hold marque autocross events, although many of these events are open to any car owner provided they first join the club.  Each local club has its own membership rules.
