Last night, all us History Buffs lost a great friend. Gregory A. Coco, a longtime park ranger at Gettysburg and gifted author of many books, lost his long battle with cancer. I was only acquainted with Greg, but his books that I read and his tours which I attended taught me an incalculable amount of history concerning the Battle of Gettysburg and the American Civil War. Greg was known for his humor and great knowledge. He once jokingly called me "one of the disciples" of Gettysburg History, one who carries on the stories of the past so that others may learn from them as well. Nevertheless, that meant a lot to me. He will be truly missed. Rest in peace, Greg.
