There was a special moment Friday, May 25 during the end-of-year pep fest at Princeton High School. U.S. Army Infantryman Mark Thomas surprised his brother Tyler during the assembly. Mark graduated a year ago and is home from Fort Carson in Colorado on a four-day pass. Pvt. Thomas graduated from basic training at Fort Benning, Ga., on Oct. 21, 2011, before moving on to Fort Carson.
