While out playing with my GoPro's at Willow Springs Kart Track, I high sided and knocked myself unconscious.
Despite walking, talking and answering questions from medical aid, I have no recollection of the crash or anything from just prior to the event, until about half way to hospital. *Consider this when dealing with the "Walking Wounded". They may appear fine, sound fine and even answer questions, but may still be in danger.
*Warning; Not Visually Graphic, but some may find the audio track entertaining, while others may find it disturbing as I apparently quit breathing for a while.
