Well kids... in a perfect world we all know what the weather will do before it happens...
So if it rains a day or two before the meet, like it did for the Test n Tune, or SpeedWeek last year, it just gets canceled. Unfortunately most of the racing salt resides across the road, ready to be loaded on rail cars and shipped to God knows where. With very little salt left, even a minor rain will shut down the race course. Years ago we had enough salt to overcome a storm, we could be back to racing in a day... sometimes two. The SCTA had that thought last year... but the rain just kept coming.
While we all would want a lot of warning of a cancellation, I suspect the SCTA will do due diligence before they call the race that supports their racing the rest of the year. That means they will do everything in their power to make the race happen... I expect they will find a course and unless it rains hard a couple of days before will not cancel the meet.
Keep your pants on... it's over 3 weeks away
