I think they only close if its thunderstorming
It has to be pretty wet out to close. Rarely do they.
I went opening weekend. and it rained on and off. heavy at times. but still went through it. kinda adds to it even more. just dress accordingly.
Well when I went it was raining on and off. The event still went on in the rain. The best advice I can give is where protective outerwear.
