Oh, wow! I am speechless!

Still better than nothing though!

At least you had a lot of fun!
The blurryness is caused by a number of things. The shakiness of your hand, your lens and most likely the camera automatic focus system. It simply got confused of all of the complicated light changes and smoke. Without proper focus you're going to get blurry image.
btw, when I went to the Madera Fair, my friend told me how dinky it compaired to the California State Fair that you went to, lol. He lives very close to there in Elk Grove.
