Decided to just go to the track today. Soon as I got there Mike Marshall's son was landed on and suffered a severe head injury. He has been taken to Memorial Herrman in Houston by helicopter. A little later another kid broke a collarbone and was hauled off. Before he could be taken to the Hospital Rush Rawlinson had a bad fall in the back trail area and appeared to have a concussion. He was being hauled off as I left. Y'all pray for Mikes son.
