Ducks Stadium in Ozark is fortunately not where the divisional will be held, so no worries there. The Crowder Neosho site was designed for 18-wheelers to begin with, and is level and in great shape.
The Ducks lot had damage repaired over the Winter, so the site was in pretty decent condition for our May event. Here's a video of my May course with MAXQ telemetry from a STU M3:

Over the course of a month, the trucking school at Ducks added a lot of new ruts. The asphalt was never intended to support repeated trailer parking exercises, which is why the course had to single-track in the back section last weekend. The bad spots tend to stay consistent, so I don't expect problems putting an okay course there in August or October.
After the July divisional, we'll be back in Neosho for a regional event on September 27th. Unless the turnout is huge, we try to aim for six runs per entrant at our regional events. Good seat time if anyone is in the area.
