While it seems like the rain likes to fall during the Cloverdale shoot, the course and grounds get no muddier than any other shoot I have been to.
No one can control if it is going to rain at any shoot. I have attended most of the major shoots at one time or another and they all get muddy after a rain. You get that many people having fun on any club grounds, it is going to get soupy.
I feel Cloverdale sets the best course of ANY club I have ever been to. The only time I miss that shoot is when it just cant be avoided.
