SFMM Friday or Saturday

I was going to go on Saturday because it is my birthday, but I have heard that it is going to rain that day.  What are the crowds like when it rains, and would Friday be a better day to go?  Thanks.

I went last year on fri, and it was PACKED. When it rins, its not that bad, but when u go on Goliath it'll hurt ur eyes, cause they go around your face, so bring a hooded sweatshirt, and Superman wont be open, since it can't ru in the rain. If you want more like how the crowds are call (661) 255-4100

I'm going on Friday.
