I fractured T4 through T8 and hyper-extended my right thumb when I was ejected from a cart after my driving horse got startled.
We were traveling about 1-1/2 mph, I fell about 18" and knew as soon as I landed that I was broken. My helmet is still wearing the dirt that rubbed into the shell, and the foam bed liner carries the impression of the back support of the SureFit. So far I've missed 8 weeks of work. My back and thumb are still mending. I've already replaced my old Troxel with a new Troxel Liberty helmet.
