The course was lovely today. Perfect footing, every inch of the course, despite yesterday's rain.
I know this because at the lunch break, I ran the course from start box to finish flags with my sister and olympicdreams04. It was absolutely heavenly, especially to our feet.
However, I think there's rain in the forecast for Saturday -- something like a 50% chance of showers, but that shouldn't change the ground to soup, and as the previous posters says, the vendors can deal with a little mud.
