That's the point when I start to dislike autocross. We had a club in college and we'd set up a few autocrosses each semester, and the duties for designing the courses would be passed down from class to class. Generally had good times as the atmosphere was lax and the courses were well planned. Some friends and I went back as alumni to compete in one event a few years ago and it was almost undriveable; the course was waaaay too complex, had too much doubling-back over other sections, and not enough cones to give directions.
Longer courses are better IMO because they can be designed to flow much better. The course in Corey's track doesn't seem too bad.
Don't get me wrong, autocrossing is still lots of fun but I find a lot more enjoyment in track days.
