Kary:
Gary is right. Our biggest challange has been the swale crossings at the faster events, like QDE's.

I've noticed you haven't really been to too many events since Gary and I started A-X's. I wanted to point out one very important design concept Carl Scragg enlightened us to, that you may have missed in the last year and a half's absence.
Low angle, slow-approach crossings have been the rule since early 2003. If you review our designs, and if you had the fortune of driving our recent events, you'd have seen a tight chicane before the crossings, and usually an approach angle not exceeding 30-degrees.

These two factors, we've found, greatly reduce the abuses the swale have caused in the past.

(Note: We have been using the same course design for the PDS, but that is a course, and a program, managed by the CDI's. I personally don't like the crossings at the PDS course and encourage my students to come to almost a complete stop prior to the crossings, but that's another matter.)
There have been some grumblings about the courses being too tight or too slow in the last year and a half.

The reason the course is slow ... obviously .... is to prevent damage and abuse at the swale crossings, and reduce speeds at high-risk, and statistically high-incedent areas of the parking lot.

Fortunately, we haven't heard a lot of complaints and grumblings about damage to cars caused by fast swale crossings; nor excessive flat-spotting of tires due to big spins.

With the newer approach to design, damage issues appear to be a mute point.
So, I think it's safe to say our QDE courses will incorporate very cautious swale crossings, or as Gary eluded to, none at all. I strongly encourage you to come out and enjoy the day. It will be a great weekend of driving.
