Those videos are from a guy named Griz who films around the Austin-San Antonio-Dallas-Houston area. If you go to the member video post section you can see a lot of his stuff. He stated last week that he will no longer film races because of the expenses and that he is physically unable to do so. He has some illness that prevents him from working at times. I hope he gets better and decides to come back out and film. His films are notch.
