I don't think it will be dry enough by then. Not much drying weather on the way. Its pretty bad, it needs to get really really windy, I don't see it happening. I've built a reputation on honesty with the riders, and I don't plan to bullshit you now to try and make a buck.
To be clear, the whole weekend is cancelled. Its that bad. I'm not pushing off half the track so it can be worse the next time it rains. I have a million other things to do at home, in the garage, final mowing at the track. Plenty to do.
