Mark Griffin is a name I have not heard of in 10 years, The thought scares me that he is working on his flight instructor certificate. I had moved to the Dallas area to go to college and met him through friends in the Dallas area. I was scared the one time i rode in a car with him down I-30 to Rockwall. He is a good guy and this was back when his song "The City Sleeps" was playing all over the Dallas Ft.Worth metroplex. Funny guy to be around especially in a bar, he would go over to the jukebox and play his songs then try to convince the ladies that he was M.C 900 ft Jesus. I wish him the best of luck.
