I always do.
I have rode two horses that bucked - but stayed on both of them. One I was lucky I didn't fall off because I wasn't wearing a helmet. That was the first time I was on a buckin horse. (it wasn't too bad of a buck but it was still pretty interesting.)
I wish one of the other horse memebers would wear a helmet, and you would not believe her reason for not wearing one.
This is what she said, "I don't wear helmets because the last time I did wear one I fell off my horse and landed on my back, but when my head hit the ground the helmet hurt my head."
The helmet hurt my head.... Well at least you didn't have to be rushed to the Hospital!!
