I don´t really remember going to many fairs as a kid.
My mom didn´t like them and there were 5 of us in our family so it was a bit expensive.
They did take us to the circus a couple of times and it was ok.
When I grew up and moved to the States, I went to a couple of fairs there. Most of them were during the fall and in one of the fair, I got hit in the head with a ball (a baseball one) that went rogue and ended up against my skull. The one I liked the most was the one in Atlantic City, though it was almost empty because it was hot and in the middle of the afternoon.
